Subject: ath6kl: Use cfg80211_roamed_bss() to report roaming event

This is to avoid the scenario where the bss entry of the AP got
expired when reporting roaming event to current AP. As the bss
entry for the current bss is available in driver, pass this bss
to cfg80211. This fixes WARNING: at net/wireless/sme.c:586.

This patch depends on the following patch in cfg80211
"cfg80211: Fix race in bss timeout".

Empty IE buffer means that the new association is not supposed to
include extra IEs. Make sure any previously configured (Re)Association
Request frame IEs get cleared in such a case. This is based on a patch
from Shuibing.

Subject: ath6kl: Avoid taking struct as argument in ath6kl_wmi_set_ip_cmd

In this way, caller is free to pass only the value of IP addr
to configure.

In addition to this,
  * 'ips' variable data type in struct wmi_set_ip_cmd is changed
     from __le32 to __be32 in order to match network byte order.
  *  ipv4_is_multicast() is used to validate multicast ip addr.
  *  New argument if_idx is added to supply correct vif index
     to ath6kl_wmi_cmd_send().

This will be used in the next patch.

Subject: ath6kl: Send own IP addr to the firmware during WOW suspend

Firmware ARP module requires own IP addr in order to respond
to the outside world when the target is in WOW suspend state.

At present, firmware ARP module has capability to hold 2 IP addr.
So, WOW mode will be disabled if the total IP addr configured in
net_dev for our device is greater than firmware limit (MAX_IP_ADDRS)
which is 2 at this moment.

Subject: ath6kl: handle firmware names more dynamically

Currently ath6kl has just hardcoded paths to each firmware file. Change
this more dynamic by separating the the directory and file name from each
other. That way it's easier to dynamically create full paths to firmware and
code looks better. And now it's possible to remove a function needed by
devicetree code.

While at it add a structure inside struct ath6kl_hw to contain all
firmware names. I deliberately omitted board file support as
those will be handled later.

This is needed for firmware API 3.

Subject: ath6kl: add support for FW API 3

As firmware starting from 3.2.0.12 has some API changes and doesn't work
with older versions of ath6kl we need to bump up the API version. This
way we don't break anything.

Also store which version of API is used and print that during boot:

ath6kl: ar6003 hw 2.1.1 sdio fw 3.2.0.13 api 3

Subject: ath6kl: Fix panic when setting a channel

cfg80211 could pass a NULL net_device to the driver via the
set_channel() callback, when it receives a request to set the
device's channel. Not handling this case properly results in this panic:

Subject: ath6kl: Add del_station cfg80211_ops

hostapd/wpa_supplicant AP mode uses this operation to flush the station
entries. Implement this in ath6kl to avoid unnecessary warnings from
NL80211_CMD_DEL_STATION failing.

This is needed to fix current hostapd/wpa_supplicant AP operations for
frame registration. P2P GO mode already advertised these, but AP mode
was forgotten and could not be used after the hostapd/wpa_supplicant
frame registration changes.

Subject: ath6kl: Support for TCP checksum offload to firmware

The change enables offloading TCP checksum calculation to firmware.
There are still some issues with the checksum offload so better to
disable it by default until the issues are resolved.

To enable TCP checksum offload for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx on
ethtool -K <interface> rx on

To disable TCP checksum offload, for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx off
ethtool -K <interface> rx off

kvalo: indentation changes

Subject: ath6kl: send TCMD response through testmode events

ath6kl no longer knows what it is transmitting through
cfg80211_testmode, and simply passes opaque buffers between userspace
and the firmware. Leave the CONT_RX enum for backwards compatibility.

kvalo: change ATH6KL_TM_CMD_RX_REPORT to return -EOPNOTSUPP

There are maximum of seven multicast filter are supported
by hw. When the requested number of filters exceeds the
maximum supported one, multicast filtering is completely
disabled, the requested filters will be configured in
firmware and the only multicast frames that host is interested
in will be passed to host for further processing otherwise.

Subject: ath6kl: Change ielen in ath6kl_add_new_sta() from u8 to size_t

Otherwise if (ielen <= ATH6KL_MAX_IE) is dead code. It looks safe to
change the type of ielen from u8 to size_t instead of removing this
if check, this ielen can have the length of more than one ies in future.

Subject: ath6kl: Use a mutex_lock to avoid race in diabling and handling irq

Currently this race is handled but in a messy way an atomic
variable is being checked in a loop which sleeps upto ms
in every iteration. Remove this logic and use a mutex
to make sure irq is not disabled when irq handling is in
progress.

Subject: sfc: Const-qualify static data as appropriate, partly prompted by
 checkpatch

Fix the following warnings:

WARNING: struct dev_pm_ops should normally be const
WARNING: static const char * array should probably be static const char * const

Similarly const-qualify struct i2c_board_info, struct i2c_algo_bit_data,
struct efx_ethtool_stat, struct efx_mtd_ops and struct siena_nvram_type_info.

Subject: sfc: Set default parallelism to per-core by default

The previous default of per-package can be more CPU-efficient, but
users generally seem to prefer per-core.  It should also allow
accelerated RFS to direct packets more precisely, if IRQ affinity
is properly spread out.

Subject: ath6kl: Fix listen interval handling

This patch addresses a few problems with the commit:

"ath6kl: Implement support for listen interval from userspace"

* The debugfs file required for reading/writing the listen interval
  wasn't created. Fix this.

* The interface index was being hardcoded to zero. Fix this.

* Two separate parameters, "listen_interval_time and listen_interval_beacons"
  were being used. This fails to work as expected because the FW assigns
  higher precedence to "listen_interval_beacons" and "listen_interval_time"
  ends up being never used at all.

  To handle this, fix the host driver to exclusively use listen interval
  based on units of beacon intervals.

To set the listen interval, a user would now do something like this:

echo "10" > /sys/kernel/debug/ieee80211/*/ath6kl/listen_interval

kvalo: fix two checkpatch warnings

Subject: ath6kl: Add support for uAPSD

* A new APSD power save queue is added in the station structure.
* When a station has APSD capability and goes to power save, the frame
  designated to the station will be buffered in APSD queue.
* When the host receives a frame which the firmware marked as trigger,
  host delivers the buffered frame from the APSD power save queue.
  Number of frames to deliver is decided by MAX SP length.
* When a station moves from sleep to awake state, all frames buffered
  in APSD power save queue are sent to the firmware.
* When a station is disconnected, all frames bufferes in APSD power save
  queue are dropped.
* When the host queues the first frame to the APSD queue or removes the
  last frame from the APSD queue, it is indicated to the firmware using
  WMI_AP_APSD_BUFFERED_TRAFFIC_CMD.

kvalo: fix buggy handling of sks queues, made it more obvious
the user priority when wmm is disabled, remove unneed else block and
combined some variable declarations

Subject: ath6kl: Remove useless initialization in ath6kl_read_fwlogs()

ath6kl_read_fwlogs() assigns the value zero to the variable 'ret'
at the time of declaration. Later, return value of ath6kl_diag_read32()
repalces the init value. Hence removing useless zero assignment.

Subject: ath6kl: use netdev_features_t

Commit c8f44affb7 ("net: introduce and use netdev_features_t for
device features sets") added netdev_features_t to ndo_set_features.
Change ath6kl to use the new type.

This fixes a warning:

ath6kl/main.c:1170: warning: initialization from incompatible pointer type

Subject: ath6kl: fix uninitialized warning in ath6kl_process_uapsdq()

Before I commited patch c1762a3fe ("ath6kl: Add support for uAPSD") I
did a minor change how up variable is initialised in
ath6kl_process_uapsdq(). But I was sloppy and caused this compiler
warning:

txrx.c:88:5: warning: 'up' may be used uninitialized in this function

Revert my change to fix the warning.

Add testmode 2 for 6003 ART. When you insmod ath6kl_sdio.ko testmode=2, ath6kl
will load ART firmware utf.bin and testscript nullTestFlow.bin. These files
should be put in the firmware folder.

kvalo: add "ath6kl:" to the title, word wrap the commit log and remove
extra line in the code

Subject: ath6kl: add ATH6KL_CONF_UART_DEBUG

Add ATH6KL_CONF_UART_DEBUG which is set whenever uart_debug module
parameter is enabled. This way we can keep the uart_debug parameter
static when core.c file is introduced.

Subject: ath6kl: create core.c

Currently core functions are spread between various files, group all
the functions into file and rename the functions to follow the style
used elsewhere in the driver. This will make it easier to a separate core
module.

Also fix a bug where wiphy is freed too early.

From 5afa5aa79680ee107fef1195c80f5f67c54b6691 Mon Sep 17 00:00:00 2001
From: Kalle Valo <kvalo@qca.qualcomm.com>

Subject: ath6kl: get rid of AR_DBG_LVL_CHECK()

We don't need it as debug calls already have a log level and compiler
should be smart enough to optimise away the code when ath6kl debug code
is not enabled. Also it makes it easier to abstract core code to
ath6kl_core.ko.

In ath6kl_dump_registers() I had to change the debug level from ANY to IRQ
as I removed the AR_DBG_LVL_CHECK() check before calling the function.

Subject: ath6kl: convert ath6kl_dbg() and ath6kl_dbg_dump() into functions

That way it's possible to not export debug_mask outside the upcoming
ath6kl_core.ko and that makes it easier to ath6kl_core.ko in the
following patch.

Subject: ath6kl: create ath6kl_core.ko

Now ath6kl is ready for splitting core code to ath6kl_core.ko module.
This also makes it possible to link both sdio and usb code to kernel
at the same time, which earlier failed miserably.

Subject: ath6kl: add back beginnings of USB support

John Linville had to revert the part of USB support which was already
in ath6kl due to build problems in commit cb00ec382b ("ath6kl: revert
USB support"). Now that I fixed the build problems properly by adding
ath6kl_core.ko kernel module it's possible to add back the
(incomplete) USB support. This patch is a revert of John's patch and
adds back the USB code which as already in ath6kl, only difference
being minor changes in Makefile and adapting usb.c to new core
function names.

Note that USB support in ath6kl is not complete yet. This code only
makes it possible to boot firmware but as HTC layer does not yet
support USB it's not possible to send any WMI commands nor data
packets to the firmware. That will be added soon.

Subject: ath6kl: Make sure to delete rx aggregation timer in
 aggr_reset_state()

The timer which is used to flush rx aggregation frames needs to
be disabled when resetting the aggregation state. This is found
in code review.

The patch "ath6kl: create core.c" removes wiphy_free() from
ath6kl_cfg80211_cleanup() and misses to free wiphy in
ath6kl_sdio_remove(). This patch fixes this regression.

Subject: ath6kl: Define a structure for connection specific aggregation
 information

This patch just groups connection specific aggregation information
from struct aggr_info into a new structure (struct aggr_info_conn)
so that, in softAP mode, this can be used when each connected station
is made to have it's own aggregation state.

Subject: ath6kl: Fix bug in using tid given by addba/delba req events

The tid which is given in addba/delba req event is not
just tid but also muxed with the assoc id (MSB 4 bits)
which can be used to determine the corresponding connected
station in softap mode. The actual tid is LSB 4 bits. Using
the tid as it is with rx_tid[] would result in OOB or invalid
memory access in AP mode.

Subject: ath6kl: Fix bug in maintaining aggregation state in AP mode

Currently rx aggregation related states are maintained per
vif, but this will not properly work when operating in AP mode.
Aggregation is completely broken when more than one
11n stations are connected to AP mode vif. Fix this issue
by keeping station specific aggregation state in sta_list.

Date: Wed, 4 Jan 2012 19:40:39 -0800
Subject: rtlwifi: Neaten RT_ASSERT, RT_TRACE, RTPRINT, RT_PRINT_DATA macros

Make the macros a bit more readable.

Use do {...} while (0) without terminating semicolons.
Add missing terminating semicolon to a few uses.

From: Joe Perches <joe@perches.com>

Subject: rtlwifi: Standardize RT_PRINT_DATA macro and uses

Use a single printk(KERN_DEBUG to emit the header line
to avoid any possible output interleaving.

Remove unnecessary parentheses from the calling uses.
Standardize header arg without trailing \n or colon.
Fix a few pairwiase/pairwise typos.

From f30d7507a8116e2099a9135c873411db8c0a3dc6 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>

Subject: rtlwifi: Convert RT_TRACE macro to use ##__VA_ARGS__

Consolidate printks to avoid possible message interleaving
and reduce the object size.

Remove unnecessary RT_TRACE parentheses.

Miscellaneous typo and grammar fixes.
Add missing newlines to formats.
Remove duplicate KERN_DEBUG prefixes.
Coalesce formats.
Align arguments.

Subject: rtlwifi: Convert RTPRINT macro to use ##__VA_ARGS__

Consolidate printks to avoid possible message interleaving
and reduce the object size.

Remove unnecessary RTPRINT parentheses.
Coalesce formats.
Align arguments.

From 9d833ed752e91c71792dd8ebfd0f865e6a568a37 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>

Subject: rtlwifi: Convert RT_ASSERT macro to use ##__VA_ARGS__

Consolidate printks to avoid possible message interleaving
and reduce the object size.

Remove unnecessary RT_ASSERT parentheses.
Align arguments.
Coalesce formats.
Remove unnecessary __func__ use as the macro uses it.

Subject: rtlwifi: add CONFIG_RTLWIFI_DEBUG to remove all of the debug logging
 code

It does seem odd though to have a DBG_EMERG and not always
emit it.

What might also be useful for any embedded use is to add
CONFIG_RTLWIFI_DEBUG to conditionally remove all of the
debug logging code to reduce the largish object size.

This reduces the object size by about 1/3 (250KB)
when CONFIG_RTLWIFI_DEBUG is not set.

not sure how it happen, but adding the sanity check to prevent memory
corruption

Subject: rtlwifi: rtl8192c_common: rtl8192de: Check for allocation failures

In https://bugzilla.redhat.com/show_bug.cgi?id=771656, a kernel bug was
triggered due to a failed skb allocation that was not checked. This event
lead to an audit of all memory allocations in the complete rtlwifi family
of drivers. This patch fixes the rest.

Subject: rtl8192cu: Remove dead code never selected

The original driver contained some conditional code that was not selected,
but was not deleted in case it would be used later. That code can now be
removed.

Subject: drivers/net/wireless/mwifiex/scan.c: convert GFP_KERNEL to GFP_ATOMIC

The function is called with locks held and thus should not use GFP_KERNEL.

The semantic patch that makes this report is available
in scripts/coccinelle/locks/call_kern.cocci.

More information about semantic patching is available at
http://coccinelle.lip6.fr/

On carl9170, HW encryption is disabled on IBSS; the mac80211
software-based encryption is used instead. As mac80211 supports IBSS
RSN (per-STA GTK), claim its support in the carl9170 PHY.

Subject: mwifiex: use bss_type and bss_num to retrieve priv

Current implementation, for retrieving priv from adapter,
uses bss_index. In multi interface environment supporting
different types, bss_index may not be unique.

Use bss_type along with bss_num to retrieve the priv.
bss_index is removed with this change.

Subject: mwifiex: derive priv from net_device instead of wiphy

Currently mwifiex_private pointers are derived from wiphy
structures. This will always work as long as there is only
one net_device associated with one wiphy. In scenarios where
there are multiple net_devices associated with single
wiphy, one should use net_device to derive the priv.

Subject: carl9170: remove eeprom data injection option

In the early days, this was a quite useful software
feature for testing different regdomains and chain
configurations without adding debugfs cruft into
the driver. Nowadays, the driver's phy code seems
to be stable and there's no need for it anymore.
Therefore I decided to removed altogether.

Subject: brcm80211: Convert printk(KERN_DEBUG to pr_debug

Use pr_debug to allow dynamic debugging to work.

Move an #endif to allow brcmf_dbg_hex_dump
to be outside the #if/#endif block.
Move a const char* declaration to be inside a
pr_debug so the function doesn't need a #if/#endif
block.
Don't use temporaries in debugging functions so
the code can be optimized away.

Subject: xen/netfront: add netconsole support.

add polling interface to xen-netfront device to support netconsole

This patch also alters the spin_lock usage to use irqsave variant.
Documentation/networking/netdevices.txt states that start_xmit
can be called with interrupts disabled by netconsole and therefore using
the irqsave/restore locking in this function is looks correct.

From 9b28ecd66b391349d3492574500f978566195454 Mon Sep 17 00:00:00 2001

Subject: net: usb: qmi_wwan: New driver for Huawei QMI based WWAN devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some WWAN LTE/3G devices based on chipsets from Qualcomm provide
near standard CDC ECM interfaces in addition to the usual serial
interfaces.   The Huawei E392/E398 are examples of such devices.

These typically cannot be fully configured using AT commands
over a serial interface.  It is necessary to speak the proprietary
Qualcomm MSM Interface (QMI) protocol to the device to enable the
ethernet proxy functionality.

The devices embed the QMI protocol in CDC on the control interface,
using standard CDC commands and notifications. The do not otherwise
use CDC commands for the ethernet function.  This driver does
therefore not need access to any other aspects of the control
interface than the descriptors attached to it.

Another driver, cdc-wdm, will provide userspace access to the
QMI protocol independently of this driver.  To facilitate this,
this driver avoids binding to the control interface, and uses
only the associated data interface after parsing the common CDC
functional descriptors on the control interface.

You will want both the cdc-wdm and option drivers as companions to
this driver, to have full access to all interfaces and protocols
exported by the device.

Subject: e1000e: cleanup Rx checksum offload code

1) cleanup whitespace in e1000_rx_checksum() function header comment
2) do not check hardware checksum when Rx checksum is disabled
3) reduce duplicated calls to le16_to_cpu() by just using it within
   e1000_rx_checksum() instead of in each call to the function

v2: use swab16 instead of le16_to_cpu & htons and corrected type for the
passed-in csum

From 70495a500d787c0c90a136acf454cb7d0eecd82e Mon Sep 17 00:00:00 2001
From: Bruce Allan <bruce.w.allan@intel.com>
Date: Wed, 11 Jan 2012 01:26:50 +0000
Subject: e1000e: add Receive Packet Steering (RPS) support

Enable RPS by default.  Disallow jumbo frames when both receive checksum
and receive hashing are enabled because the hardware cannot do both IP
payload checksum (enabled when receive checksum is enabled when using
packet split which is used for jumbo frames) and provide RSS hash at the
same time.

v2: added ethtool command to query flow hashing behavior per Ben Hutchings
    and changed the type of rsskey to cleanup the setting of the register
    array and avoid unnecessary casts (as pointed out by Joe Perches).
    The long error messages are not changed since there is nothing in
    the kernel ./Documentation that suggests the preferred method for
    dealing with long messages other than to never break strings; leaving
    them as-is for now.

Subject: e1000e: convert head, tail and itr_register offsets to __iomem
 pointers

The Tx/Rx head and tail registers and itr_register are always at known
addresses based on the __iomem address at which the PCI region (from BAR 0)
is mapped and known offsets within the region for each of these registers.
Store and use the full address rather than just the region offset to reduce
unnecessary address calculations.  Also, change current u8 __iomem pointers
to void __iomem pointers.

Subject: e1000e: default IntMode based on kernel config & available hardware
 support

Based on a patch from Prabhakar Kushwaha <prabhakar@freescale.com>, set
appropriate default interrupt mode dependent on whether CONFIG_PCI_MSI
is enabled in the kernel configuration and if the hardware supports
MSI-X.  Set the module parameter log message accordingly.

Subject: e1000e: use default settings for Tx Inter Packet Gap timer

Use the default hardware values for TIPG except for 80003es2lan(*).  The
code that is removed in this patch is either unnecessarily writing the TIPG
register with the hardware default values for some devices (82571/2/3/4) or
writing the wrong value for others (ICH/PCH LOMs).  The only change in
functionality is setting the correct default TIPG for the latter devices.

(*) The correct value for 80003es2lan is already set properly in
e1000_init_hw_80003es2lan() and e1000_cfg_kmrn_{10_100|1000}_80003es2lan(),
and the unused flag FLAG_TIPG_MEDIUM_FOR_80003ESLAN is removed.

Subject: e1000e: use hardware default values for Transmit Control register

This code snippet is simply writing default values to the register which is
unnecessary since the values are programmed into the register by default.
There is a special case for 80003es2lan needing the Retransmit on Late
Collision bit set but that is also done in e1000_init_hw_80003es2lan().

Enable the use of up to three hardware queues for transmission. The queues
are always dequed round robin (i.e. strict priority, PFC and ETS are not
supported). This does allow the allocation of a seperate HW queue for low
volume, high priority traffic which will be serviced more promptly.

Subject: bnx2x: Removing indirect register access

In virtualized environments indirect access to the device may not be supported
(depending on the Hypervisor type). Indirect device access was used since in
some harware contexts (i.e. certain chipset and BIOS) every access the driver
makes across the pci is followed by a BIOS initiated Zero Length Read to the
same address. When accessing widebus registers this zero length read corrupts
the serialization of the read/write sequence resulting with errors. To avoid
this problem widebus registers are always accessed via the DMAE or the indirect
interface. However, the 57712x and 578xx devices intercept the zero length read
and so using the indirect interface with these devices is not necessary. Since
PDA is only supported for 57712x and 578xx the indirect access to device was
restricted to 57710 and 57711x.

BDF was obtained from kernel but since in virtualized environment
(e.g. physical device assigment in KVM) the function number may
not be the real one, the info must be obtained from the device.

Subject: bnx2x: Loaded Firmware Version Validation

In a virtualized environment it is possible for a loading driver to discover
that Firmware is already loaded to the device, and that this FW does not match
its own. This can happen for example if different Physical Functions are
Assigned to different VMs in which different driver versions are loaded. The
code in this patch ensures that only drivers with matching FW are loaded over
the device, and that in the case described above where the Firmware version
doesn't match the driver load is aborted.

Subject: bnx2x: Lock PF-common resources

Use hardware locks to protect resources common to several Physical Functions. In
a virtualized environment the RTNL lock only protects a PF's driver against
the PFs sharing it's VMs with regard to device resources. Other PFs may reside
in other VMs under other OSs, and are not subject to the lock. Such resources
which were previously protected implicitly by the RTNL lock must now be
protected explicitly with dedicated HW locks.

From 889b9af34f986138eebebfe781567cb950b3a22b Mon Sep 17 00:00:00 2001
From: Ariel Elior <ariele@broadcom.com>

Subject: bnx2x: Track active PFs with bitmap

The recovery register (to which a hardware lock has been added in previous
patch) is used amongst other things to track the active PFs. The old
implementation which used a per path counter is not viable in a virtualized
environment where a pf may increment the counter and then have the kernel
crash around it preventing the counter from ever reaching zero.
In the new implementation the scenario described will result in the PF timing
out against the mcp, which will clear the PF's bit in the bitmask allowing
recovery process to proceed.

From 95c6c6165eaf5a031bcf31606e081c72e4acdeb8 Mon Sep 17 00:00:00 2001
From: Ariel Elior <ariele@broadcom.com>

Subject: bnx2x: Recovery flow bug fixes

1. Sample mcp pulse and mcp sequence in nic load instead of in init_one
as they may change by the time we want to use them.

2. Allow cnic to access device during nic load (by adding a new "LOADING" state
to recovery flow). This prevents the unnecessary cnic timeout which resulted
by cnic attempting to access because nic is loading, but being blocked because
of the Recovery state.

3. Issue 'fake' driver load command to mcp when last driver unloads to prevent
mcp from taking ownership. When recovery is complete unload fake driver to
allow mcp to initialize the hardware before first driver loads.

Subject: be2net: allocate more headroom in incoming skbs

Allocation of 64 bytes in skb headroom is not enough if we have to pull
ethernet + ipv6 + tcp headers, and/or extra tunneling header.

Its currently not noticed because netdev_alloc_skb_ip_align(64) give us
more room, thanks to power-of-two kmalloc() roundups.

Make sure we ask for 128 bytes so that side effects of upcoming patches
from Ian Campbell dont decrease benet rx performance, because of extra
skb head reallocations.

Subject: sfc: Remove fallback for invalid permanent MAC address

By the time we look at the MAC address in efx_probe_port(), either the
driver or the firmware has already validated the board configuration.
The possibility of having an invalid MAC address just isn't worth
considering.  It certainly isn't worth having a compile-time option
for this.

Subject: sfc: Make handling of MC reboot more reliable

When the MC reboots, either as part of a firmware upgrade or due to a
bug, it attempts to complete (with an error) any requests that were
outstanding before the reboot.  Since there is an inherent race
condition in checking this, it will also write to a status word in
shared memory.

If we look at each of these separately, we may detect each reboot
twice, resulting in a spurious command failure after a firmware
upgrade or frustrating recovery from a firmware bug.  Instead, if a
request completion indicates a reboot, we must poll and clear the
status word.

This bug was previously masked by use of an incorrect address for the
status word.  Fix that, using the definition now included in
mcdi_pcol.h.

Subject: sfc: Hold efx_nic::stats_lock while reading efx_nic::mac_stats

efx_nic::stats_lock is used to serialise stats updates, but each
reader was dropping it before it finished reading efx_nic::mac_stats.

If there were concurrent stats reads using procfs, or one using procfs
and one using ethtool, an update could race with a read.  On a 32-bit
system, the reader could see word-tearing of 64-bit stats (32 bits of
the old value and 32 bits of the new).

Subject: sfc: Merge efx_mac_operations into efx_nic_type

No NICs need to switch efx_mac_operations at run-time, and the MAC
operations are fairly closely bound to NIC types.

Move efx_mac_operations::reconfigure to efx_nic_type::reconfigure_mac
and efx_mac_operations::check_fault fo efx_nic_type::check_mac_fault.
Change callers to call through efx->type or directly if the NIC type
is known.

Remove efx_mac_operations::update_stats.  The implementations for
Falcon used to fetch MAC statistics synchronously and this was used by
efx_register_netdev() to clear statistics after running self-tests.
However, it now only converts statistics that have already been
fetched (and that only for Falcon), and the call from
efx_register_netdev() has no effect.

Subject: sfc: Merge efx_mcdi_mac_check_fault() and efx_mcdi_get_mac_faults()

The latter is only called by the former, which is a very short
wrapper.  Further, gcc 4.5 may currently wrongly warn that the
'faults' variable may be used uninitialised.

Subject: sfc: Remove efx_nic_type::push_multicast_hash operation

Both implementations of efx_nic_type::reconfigure_mac operation
push the multicast hash filter to the hardware.  It is therefore
redundant to call efx_nic_type::push_multicast_hash as well.

efx_mcdi_mac_reconfigure() also uses this operation, but the
implementation for Siena just uses MCDI anyway.  Merge that into
efx_mcdi_mac_reconfigure().

Subject: sfc: Consistently test DEBUG macro, not EFX_ENABLE_DEBUG

The netif_dbg() macro is defined in <linux/netdevice.h>.  If the DEBUG
macro is defined, it logs a message at 'debug' level, otherwise it
does nothing.

In net_driver.h we define DEBUG if EFX_ENABLE_DEBUG is defined, but
this is too late for those source files that already got a
definition of netif_dbg() by including <linux/netdevice.h>

Get rid of EFX_ENABLE_DEBUG, and only define and test DEBUG.

In mtd.c, we do not use DEBUG as a condition flag but are forced to
use the DEBUG macro-function from <linux/mtd/mtd.h>.  Undefine DEBUG
before including it.

Subject: sfc: Correct interrupt timer quantum for Siena (normal and turbo
 mode)

We currently assume that the timer quantum for Siena is 5 us, the same
as for Falcon.  This is not correct; timer ticks are generated on a
rota which takes a minimum of 768 cycles (each event delivery or other
timer change will delay it by 3 cycles).  The timer quantum should be
6.144 or 3.072 us depending on whether turbo mode is active.

Replace EFX_IRQ_MOD_RESOLUTION with a timer_quantum_ns field in struct
efx_nic, initialised by the efx_nic_type::probe function.

While we're at it, replace EFX_IRQ_MOD_MAX with a timer_period_max
field in struct efx_nic_type.

Subject: sfc: Remove dependence on NAPI polling in efx_test_eventq_irq()

We cannot safely assume that the NAPI handler will complete within the
20 ms that we allow for the event self-test.  The handler may be
deferred for longer than this, particularly on realtime kernels.

Instead, check whether either an event has been handled or (as in the
old failure path) whether an interrupt has been received and an event
has been delivered but not yet handled.  Use napi_disable() to
synchronize with the NAPI handler before checking, since it will
clear events before updating eventq_read_ptr.

Remove the test result chan.N.eventq.poll, since it is not an error
if the NAPI handler does not run during the test.

Subject: Partly revert "sfc: Handle serious errors in exactly one interrupt
 handler"

This reverts commit 6369545945b90daa1a73fca174da9194c398417c in
drivers/net/ethernet/sfc/falcon.c.

Unlike the INT_ISR0 register on later controller revisions, the
NET_IVEC_INT_Q bits written to memory are only ever set for
interrupting event queues, not for any other interrupt sources.

By definition there can only be one legacy interrupt handler per
function, so there is no need to worry about detecting a fatal
interrupt more than once.

Subject: sfc: Clean up test interrupt handling

Interrupts are normally generated by the event queues, moderated by
timers.  However, they may also be triggered by detection of a 'fatal'
error condition (e.g. memory parity error) or by the host writing to
certain CSR fields as part of a self-test.

The IRQ level/index used for these on Falcon rev B0 and Siena is set
by the KER_INT_LEVE_SEL field and cached by the driver in
efx_nic::fatal_irq_level.  Since this value is also relevant to
self-tests rename the field to just 'irq_level'.

Avoid unnecessary cache traffic by using a per-channel 'last_irq_cpu'
field and only writing to the per-controller field when the interrupt
matches efx_nic::irq_level.  Remove the volatile qualifier and use
ACCESS_ONCE in the places we read these fields.

Subject: sfc: Add hwmon driver for boards using SFC9000-family controllers

The SFC9000-family controllers have firmware to manage all board
peripherals including temperature, heat sink continuity and voltage
sensors.  The firmware reports sensor alarms, which we log, and
will shut down the board if necessary.

Some users may want to monitor their boards more closely, so add an
hwmon driver that exposes all sensors reported by the firmware.  Move
efx_mcdi_sensor_event() into the new file so it can share the array of
sensor labels with the hwmon driver.

The out-of-tree version of the sfc driver used to run a self-test on
each device before registering it.  Although this was never included
in-tree, some functions have checks for this special case which is not
really possible.

Subject: sfc: Make all MAC statistics consistently 64 bits wide

Currently we use type u64 for byte counts, which can very quickly
exceed 2^32, and unsigned long for packet counts, which do not.  But
it can still take only 20-something minutes to send or receive 2^32
packets, and not all tools properly handle overflow even if they
sample more often than this.

The MAC statistics are all updated synchronously, so it costs very
little to make them all 64-bit regardless of native word size.

Subject: e1000e: disable Early Receive DMA on ICH LOMs

Internal stress testing with jumbo frames shows the reliability of ICH9 and
ICH10D devices is improved in certain corner cases by disabling the Early
Receive feature. To reduce the performance impact caused by disabling this
feature, the packet buffer sizes and relevant flow control settings are
modified accordingly.

Subject: e1000e: update workaround for 82579 intermittently disabled during
 S0->Sx

The workaround which toggles the LANPHYPC (LAN PHY Power Control) value bit
to force the MAC-Phy interconnect into PCIe mode from SMBus mode during
driver load and resume should always be done except if PHY resets are
blocked by the Manageability Engine (ME).  Previously, the toggle was done
only if PHY resets are blocked and the ME was disabled.

The rest of the patch is just indentation changes as a consequence of the
updated workaround.

Subject: e1000e: ICHx/PCHx LOMs should use LPLU setting in NVM when going to
 Sx

When going to Sx with an ICHx/PCH device, the default Low Power Link Up
(LPLU, a.k.a. reverse auto-negotiation) behavior should be whatever is set
in the NVM.  However, the function e1000_suspend_workarounds_ich8lan()
called when going to Sx always enabled LPLU in all power states.

Subject: e1000e: concatenate long debug strings which span multiple lines

To ease searching for debug message strings, concatenate strings that span
multiple lines even if the resulting line exceeds 80 columns; these will
not cause checkpatch warnings.

Also, add '\n' and remove unnecessary '\r' from a few debug strings.

Subject: e1000e: split lib.c into three more-appropriate files

The generic lib.c file contains code relative to the various MACs, NVM and
Manageability supported by the driver.  This patch splits the file into
three which are specific to those areas similar to how the PHY-specific
code is in phy.c and code specific to the 80003es2lan, 8257x, and ichX
MAC families are in their own files.  The generic code that is applicable
to all MAC/PHY parts supported by the driver remains in netdev.c, param.c
and ethtool.c files.  No change in functionality, just moving code
around for ease of maintenance, with some whitespace and other checkpatch
cleanups.

Subject: r8169: remove rtl8169_reinit_task.

I see no good reason to keep both rtl8169_reinit_task and rtl8169_reset_task:
- rtl8169_reinit_task adds a software failure point which does relate to
  any hardware state
- they handle hardware the same. Remember that rtl8169_reinit_task was
  introduced in the 8169 only era to handle PCI errors way before the 8168
  asked for pll and firmware ops and compare :

      rtl8169_reinit_task     |    rtl8169_reset_task

Subject: r8169: stop delaying workqueue.

Though motivated by the move of the driver to a single work queue of
sequential events and removal of hard irq processing, it looks safe as
a standalone change.

Subject: mac80211: make beacon filtering per virtual interface

Due to firmware limitations, we may not be able to
support beacon filtering on all virtual interfaces.
To allow this in mac80211, introduce per-interface
driver capability flags that the driver sets when
an interface is added.

Subject: mwifiex: pass priv pointer instead of adapter

Pass mwifiex_private pointer directly to wmm_add_buf_txqueue()
instead of passing adapter and then deriving priv again in
mwifiex_get_priv_by_id(). This reduces a 'for' loop in TX path.

Subject: r8169: remove work from irq handler.

The irq handler was a mess.

See 7ab87ff4c770eed71e3777936299292739fcd0fe ("via-rhine: move work from
irq handler to softirq and beyond") for similar changes. One can notice:
- all non-napi tasks are explicitely scheduled trough a single work queue.
- hiding software tx queue start behind the rtl_hw_start method is mildly
  natural. Move it in the caller where needed.
- as can be seen from the heavy use of bh disabling locks, the driver is
  not safe for irq context messages with netconsole. It is still quite
  usable for general messaging though. Tested ok with concurrent registers
  dump (ethtool -d) + background traffic + "echo t > /proc/sysrq-trigger".

Tested with old PCI chipset, PCIe 8168 and 810x:
- XID 0c900800 RTL8168evl/8111evl
- XID 18000000 RTL8168b/8111b
- XID 98000000 RTL8169sc/8110sc
- XID 083000c0 RTL8168d/8111d
- XID 081000c0 RTL8168d/8111d
- XID 00b00000 RTL8105e
- XID 04a00000 RTL8102e

As a side note, the comments in f11a377b3f4e897d11f0e8d1fc688667e2f19708
("r8169: avoid losing MSI interrupts") does not seem completely clear: if
I hack the driver further to stop acking the irq link event bit, MSI
interrupts keep being delivered (RTL8168b/8111b, XID 18000000).

Subject: sfc: Use a more sensible cast in efx_rx_buf_offset()

This function returns the page offset of the buffer, which can be
calculated based on either its DMA address or its virtual address.  It
used to use the virtual address and we would cast that to unsigned
long, as anything smaller would result in a compiler warning.  Now
that it's using the DMA address we should use unsigned int, matching
the return type.  It is also unnecessary to use __force.

Subject: drivers/net: strip unused module code from sun3_82586.c

This code is clearly unused, since it has a #error right
in it.  Given the vintage of sun3 hardware, it is probably
safe to assume that there is little interest in adding new
functionality to the driver now, so just delete the unused
block of code.

Subject: ath6kl: fix testmode when fw-2.bin or fw-3.bin is used

Testmode (TCMD and ART) was not enabled when fw-2.bin or fw-3.bin files
were available, fix that by fetching testmode file just after the
board file but before rest of the firmware files are fetched.

I also added testmode field to struct ath6kl and moved the module parameter
to core.c. Now all module parameters are grouped in one place.

Subject: ath6kl: Fix kernel panic during rx aggregation

"ath6kl: Define a structure for connection specific aggregation information"
introduces this. In aggr_conn_init(), vif->aggr_cntxt is assigned to
aggr_conn->aggr_info, but vif->aggr_cntxt is not initialized at this
point, this would end up accessing an invalid pointer in aggregation
receive path. Fix this by passing the correct aggr_info to aggr_conn_init().
The panic trace would look like.

Subject: ath6kl: Re-architect suspend mode handling in ath6kl_sdio_suspend

Using this patch, the user can bypass existing auto
suspend mode selection logic and force ath6kl to enter
into the suspend mode what he/she wants.

If the user doesn't choose any suspend mode while doing
insmod of the driver, auto suspend mode selection logic
will kick in and choose suspend mode based on the host
SDIO controller capability.

Generic module parameter is required to specify suspend
mode including Deep Sleep and WOW while doing insmod.
Renaming existing mod param variable suspend_cutpower
would be sufficient to meet this requirement.

New module parameter suspend_mode can take any one of
the below suspend state,
   1. cut power
   2. deep sleep
   3. wow

From d91e8eee046e0d4ae7a8a585616b5ce800f54568 Mon Sep 17 00:00:00 2001

Subject: ath6kl: Configure WOW patterns while going to wow_suspend

First preference is given to the user configured WOW patterns.
If the user doesn't configure any patterns (for ex, via iw command),
the default patterns will be configured based on the current mode
(vif->nw_type) while going to WOW suspend.

Summary of changes:

  * ath6kl_wow_ap() is added to configure the below default
    patterns when the system enters into WOW suspend in AP mode.
      + Unicast IP, EAPOL-like and ARP packet pattern
      + ARP packet pattern
      + mDNS/SSDP/LLMNR pattern
      + DHCP broadcast pattern

 * ath6kl_wow_sta() is added to configure the below default
   patterns when the system enters into WOW suspend in STA mode.
      + Unicast packet pattern
      + mDNS/SSDP/LLMNR pattern

  * Move the user provided WOW patterns configuration code
    from ath6kl_wow_suspend() to a separate function called
    ath6kl_wow_usr().

  * Two argument variable's ('filter' and 'mask) data type in
    ath6kl_wmi_add_wow_pattern_cmd() are changed from 'u8 *' to
    'const u8 *'. This is needed to make all pattern and mask
    arrays to be 'static const u8' in the caller function.

  * New conditional check is added to make sure user
    configured pattern count is within the limit (WOW_MAX_FILTERS_PER_LIST).

Subject: ath6kl: Wait for host sleep mode cmd processed event during WOW
 suspend

For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host),
the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as
an acknowledgement to the host.

In order to being sync with the firmware, the host has to wait for
WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to
the suspend state. This patch ensures ath6kl_wow_suspend() waits
until it gets this event after sending set host sleep mode command.

This patch adds,
 * New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in
   WMI event table.
 * New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx()
   to process the event.

Subject: ath6kl: Return a proper error code when not in connected state

Error code ENOTCONN is more suitable than EINVAL to report
when the driver is not in connected state in ath6kl_wow_suspend().

I found this during code review.

Subject: rtlwifi: Move pr_fmt macros to a single location

Although the rtlwifi family of devices contains 11 copies of the pr_fmt
macro, the macro is not defined for all routines that need it. By moving
the macro to wifi.h, a single copy is available for all routines.

Subject: iwlwifi: fix uCode event tracing

Fix multiple bugs in event tracing:

1) If you enable uCode tracing with the device down,
   it will still attempt to access the device and
   continuously log "MAC is in deep sleep!" errors.
   Fix this by only starting logging when the device
   is actually alive.

2) Now you can set the flag when the device is down,
   but logging doesn't happen when you bring it up.
   To fix that, start logging when the device comes
   alive. This means we don't log before -- we could
   do that but I don't need it right now.

3) For some reason we read the error instead of the
   event log -- use the right pointer.

4) Optimise SRAM reading of event log header.

5) Fix reading write pointer == capacity, which can
   happen due to racy SRAM access

6) Most importantly: fix an error where we would try
   to read WAY too many events (like 2^32-300) when
   we read the wrap counter before it is updated by
   the uCode -- this does happen in practice and will
   cause the driver to hang the machine.

7) Finally, change the timer to 10ms instead of 100ms
   as 100ms is too slow to capture all data with a
   normal event log and with 100ms the log will wrap
   multiple times before we have a chance to read it.

Subject: iwlwifi: always restrict scan dwell in P2P

Whenever the PAN (P2P) context is active, it
has timers in the uCode that prevent sleep,
so scanning can't be out of channel for more
than the beacon interval programmed into the
device.

Before this patch, a full scan including any
passive channels when P2P was active would
stall forever because it wouldn't find time
to execute the passive requests (for default
beacon intervals of 100 TU.)

Subject: rtlwifi: Convert to asynchronous firmware load

This patch addresses a kernel bugzilla report and two recent mail threads.

The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632,
which reports a udev timeout on boot.

The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/
linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a
suspend/resume cycle for rtl8192cu.

The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2)
concerned changes in udev that break drivers that delay while firmware is loaded
on modprobe.

This patch converts all rtlwifi-based drivers to use the asynchronous firmware
loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common
callback routine. Driver rtl8192se needs different handling of the firmware,
thus it has its own code.

From 41de8d4cff21a2e81e3d9ff66f5f7c903f9c3ab1 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Sun, 29 Jan 2012 13:47:52 +0000
Subject: drivers/net: Remove alloc_etherdev error messages

alloc_etherdev has a generic OOM/unable to alloc message.
Remove the duplicative messages after alloc_etherdev calls.

Subject: ixgbe: Add module parameter to allow untested and unsafe SFP+ modules

The X520 family of network devices, with the 82599 chip, support a
small number of Intel-verified SFP+ modules on their NICs.  To maintain
stability and quality, the current devices restrict untested 3rd party
SFP+ modules.

This patch introduces a module parameter for ixgbe to allow these untested
modules at the user's peril.  It also includes a warning to the syslog
alerting users that the modules aren't supported, and results may
vary.

Subject: be2net: add descriptions for stat counters reported via ethtool

Also rename a few counters appropritely and delete 2 counters that are not
implemented in HW.

vlan_mismatch_drops does not exist in BE3 and is accounted for in
address_mismatch_drops. Do the same thing for BE2 and Lancer.

Subject: ath6kl: fix compiler warning in ath6kl_init_hw_params()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both Luis and John reported that they see a compiler warning:

drivers/net/wireless/ath/ath6kl/init.c: In function 'ath6kl_init_hw_params':
drivers/net/wireless/ath/ath6kl/init.c:1377:26: warning: ‘hw’
may be used uninitialized in this function

Oddly enough I have never seen it. But AFAICT the code is correct and
hw is not used uninitalized so add uninitialized_var() to inform that to
the compiler.

Subject: iwlwifi: allocate the transport from the bus layer

Change the way we alloc the transport on the way.
Since the transport is allocated from a bus specific area, we can
give the bus specific parameters (i.e. pci_dev for PCI) to the
transport. This will be useful when the bus layer will be killed.

Subject: iwlwifi: give trans to all the read / write functions

From now on, the transport layer in charge of providing access to the
device. So change all the driver to give a pointer to the transport
to all the low level functions that actually access the device.

Subject: iwlwifi: introduce trans_ops->stop_hw

This handler stops the HW and puts it in low power state.
It will allow to clean up the flows in the upper layers.

Subject: iwlwifi: consolidate the start_device flow

Now there is only one transport function that launch a specific fw:
trans_ops->start_fw. This one replaces trans_ops->start_device and
trans_ops->kick_nic. The code that actually loads the fw to the
device has been moved to the transport specific code.

Subject: iwlwifi: stop_hw replace enable_rfkill_int

This trans_ops->stop_hw leaves the RFKILL interrupt enabled,
we can call that one instead of enable_rfkill_int. By that,
we reduce the numbers of acceesses to the NIC from the upper
layers.

The message was misleading when a queue is deactivated. The fifo
number is irrelevant then, so don't print it.

Subject: can: dev: let can_get_echo_skb() return dlc of CAN frame

can_get_echo_skb() is usually called in the TX complete handler.
The stats->tx_packets and stats->tx_bytes should be updated there, too.
This patch simplifies to figure out the size of the sent CAN frame.

Subject: can: flexcan: Fix CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK

Currently the flexcan driver uses hardware local echo. This blindly
echos all transmitted frames to all receiving sockets, regardless what
CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK are set to.

This patch now submits transmitted frames to be echoed in the transmit
complete interrupt, preserving the reference to the sending
socket. This allows the can protocol to correctly handle the local
echo.

Further this patch moves tx_bytes statistic accounting into the tx_complete
handler.

Subject: enic: Enable support for multiple hardware receive queues

This patch enables support for multiple receive queues. If multiple receive
queues are used ingress traffic is hashed into one of the receive queues based
on IP or TCP or both headers. The max number of supported receive queues per
vnic is 8.

Implement RX flip buffer in the cfhsi_rx_done function,
piggy-backed frames is also supported.
This gives a significant performance gain for CAIF over HSI.

Subject: bnx2: Add missing memory barrier in bnx2_start_xmit()

Sync DMA descriptor before hitting the TX mailbox for weak memory model
CPUs.

There has been discussions several years ago about this.  Some believe
that writel() should guarantee ordering.  Others want explicit barriers
if necessary.  Today writel() does not have the ordering guarantee and
many other drivers use explicit barriers.

Subject: cnic: Add FCoE parity error recovery

When bnx2x returns error on FCoE SPQ messages, generate an error
completion to bnx2fc immediately to speed up error recovery.  This
will eliminate length timeouts and spped up the reset of the device.

From 21a4e46995fa1a76281ac0281ff837f706231a37 Mon Sep 17 00:00:00 2001
From: Pradeep A Dalvi <netdev@pradeepdalvi.com>
Date: Sun, 5 Feb 2012 02:50:10 +0000
Subject: netdev: ethernet dev_alloc_skb to netdev_alloc_skb

Replaced deprecating dev_alloc_skb with netdev_alloc_skb in drivers/net/ethernet
  - Removed extra skb->dev = dev after netdev_alloc_skb

From c056b734e54e12f38f34a2583a4824e6cecc16c1 Mon Sep 17 00:00:00 2001
From: Pradeep A Dalvi <netdev@pradeepdalvi.com>
Date: Sun, 5 Feb 2012 02:50:38 +0000
Subject: netdev: ethernet dev_alloc_skb to netdev_alloc_skb

Replaced deprecating dev_alloc_skb with netdev_alloc_skb in drivers/net/ethernet
  - Removed extra skb->dev = dev after netdev_alloc_skb

Subject: mwifiex: fix NULL pointer dereference in set_channel()

In set_channel() callback handler, "priv" pointer is derived from
net_device. Sometimes net_device pointer coming from the stack
is NULL which causes kernel crash.
This patch fixes the problem by deriving "priv" from wiphy
when net_device pointer is NULL.

Subject: rtlwifi: Fix PCI probe error path orphaned memory

Memory allocated by ieee80211_alloc_hw() will get orphaned
if any subsequent initializations fail.

Also don't pci_set_drvdata(pdev, NULL) until just before disabling
the PCI device. Functions called by rtl_deinit_core(hw) may eventually need
the context (when its actually implemented).

3) Declare "ul_temp" variable as u16 instead of u32 to avoid

Subject: mwifiex: update correct dtim_period in dump_station()

Earlier we were using dtim period extracted from scan response
buffer provided by FW in scan operation. But it is observed that
sometimes the buffer doesn't contain dtim period tlv, and wrong
value (0) was sent to user space.

After association FW will start listening to beacon frames of
connected AP and store dtim period. Therefore we can get it from
FW in dump_station() instead of using wrong value obtained in
scanning.

Redundant code after adapting new approach for dtim period is
also removed in this patch.

From ab50a2a430693b0961dc7b7d9fe2a4bd77d11ea6 Mon Sep 17 00:00:00 2001
From: Mitch A Williams <mitch.a.williams@intel.com>
Date: Sat, 14 Jan 2012 08:10:50 +0000
Subject: igbvf: refactor Interrupt Throttle Rate code

The existing ITR code is broken and confusing, with lots of similarly-named
variables that do different things. Additionally, after the driver carefully
determines the optimal interrupt rate for the adapter, it then
ignores it and always writes a fixed, suboptimal value.

This patch refactors that code to make variable names more descriptive of
what they actually do, and then actually writes the calculated result to
the hardware.

Preliminary testing shows that netperf TCP_STREAM tests goes from ~918Mbps
to ~940Mbps, and TCP_RR goes from ~2k transactions/sec up to > 8k.

Date: Tue, 31 Jan 2012 06:37:27 +0000
Subject: e1000e: cleanup - check return values consistently

The majority of the e1000e code checks most function return values using a
test like 'if (ret_val)' or 'if (!ret_val)' but there are a few instances
of 'if (ret_val == 0)'.  This patch converts the latter to the former for
consistency.

Combine two switch statements into one, convert a nebulous pointer to one
that is a bit more in keeping with the rest of the driver code and remove
some dead code (there are no 80003es2lan devices with fiber).  No change in
functionality, just cosmetic changes.

Subject: net: fec: Fix build due to wrong dev annotation

commit 21a4e469 (netdev: ethernet dev_alloc_skb to netdev_alloc_skb)
should have used "ndev" instead of "dev".

This causes the following build errors:

drivers/net/ethernet/freescale/fec.c: In function 'fec_enet_rx':
drivers/net/ethernet/freescale/fec.c:714: error: 'dev' undeclared (first use in this function)
drivers/net/ethernet/freescale/fec.c:714: error: (Each undeclared identifier is reported only once
drivers/net/ethernet/freescale/fec.c:714: error: for each function it appears in.)
drivers/net/ethernet/freescale/fec.c: In function 'fec_enet_alloc_buffers':
drivers/net/ethernet/freescale/fec.c:1213: error: 'dev' undeclared (first use in this function)

Fix it, so that fec driver can be built again.

Subject: sh-eth: use netdev stats structure and fix dma_map_single

No need to maintain a parallel net_device_stats structure in
sh_eth_private, since we have a generic one in netdev

Fix two dma_map_single() incorrect parameters, passing skb->tail instead
of skb->data. Seems that there is no corresponding dmap_unmap_single()
calls for the moment in this driver.

Subject: ath6kl: store firmware logs in skbuffs

Currently firmware logs are stored in a circular buffer, but this was
not very flexible and fragile. It's a lot easier to store logs to struct
skbuffs and store them in a skb queue. Also this makes it possible
to easily increase the buffer size, even dynamically if we so want (but
that's not yet supported).

From user space point of view nothing should change.

Subject: ath6kl: add blocking debugfs file for retrieving firmware logs

When debugging firmware issues it's not always enough to get
the latest firmware logs, sometimes we need to get logs from a longer
period. To make this possible, add a debugfs file named fwlog_block. When
reading from this file ath6kl will send firmware logs whenever available
and otherwise it will block and wait for new logs.

From b29072cc7b0e08ace48ab709c40cf6246fb2e8b0 Mon Sep 17 00:00:00 2001
From: Chilam Ng <chilamng@qca.qualcomm.com>
Date: Tue, 7 Feb 2012 01:33:00 -0800
Subject: ath6kl: prioritize Tx bundling based on AC priorities

Tx bundling is the more efficient use of SDIO bus and allows more packet
transfers with fewer bus transactions, and is a way to improve overall
throughput. However, Tx bundling has only 4 scatter request resources available.
When there are multiple traffic streams of different priorities, it's possible
that lower priority traffic may hog all the scatter requests and lock out the
higher prioirty traffic from bundling.
Tx bundling is now enabled per AC. When an AC do a scatter request and
the remaining scatter request resources is lower than a configurable
threshold, it will disable Tx bundling for all AC's of lower priorities.
When an AC has Tx bundling disabled and has no Tx bundles sent in a
consecutive and configurable number of packets, Tx bundling will be re-enabled
for that AC.

Subject: rt2x00: Introduce concept of driver data in struct rt2x00_dev.

We are getting more and more fields in struct rt2x00_dev that are
specific to one or two of the low-level drivers. Instead of putting
these fields inside the main structure and thus clobbering all low-level
drivers with these fields, introduce the concept of driver data inside
struct rt2x00_dev, whose size is indicated by the low-level driver and
which can be populated by the low-level driver.

Subject: rt2x00: Update comment on freq_offset field in struct rt2x00_dev.

The comment states that the field is only used for rt61pci and rt73usb.
However, it is now used by rt2800pci and rt2800usb as well, so the
comment is not correct anymore.

Update the comment to not state any low-level drivers anymore.

Subject: rtlwifi: Return correct failure code on error

Callers of rtl_pci_init expect zero to be returned on error. Returning
the error code leads to, amongst other things, divide by zero panics
attempting to use the ring size that is set to zero.

From 1ab0d2ec9aeb4489c05158e8a2b00bad89f67e03 Mon Sep 17 00:00:00 2001
From: "Pradeep A. Dalvi" <netdev@pradeepdalvi.com>
Date: Mon, 6 Feb 2012 11:16:48 +0000
Subject: netdev: ethernet dev_alloc_skb to netdev_alloc_skb

Replaced deprecating dev_alloc_skb with netdev_alloc_skb in drivers/net/ethernet
  - Removed extra skb->dev = dev after netdev_alloc_skb

Signed-off-by: Pradeep A Dalvi <netdev@pradeepdalvi.com>

"esize" should be signed because it can be negative here.  For example,
when we call it in netxen_parse_md_template(), it could be -1 from the
return value of netxen_md_L2Cache().

Subject: e1000e: pass pointer to hw struct for e1000_init_mac_params_XXX()

The e1000_init_mac_params_XXX() functions (where XXX is one of the three
MAC-family types 80003es2lan, 82571 and ich8lan) was not meant to require a
pointer to the adapter struct but does require a pointer to the hw struct.
Pass that pointer in to the functions instead.

Subject: ixgbe: Minor refactor of RSC

This change addresses several issue.

First I had left the use of the next and prev skb pointers floating around
in the code and they were overdue to be pulled since I had rewritten the
RSC code in the out-of-tree driver some time ago to address issues brought
up by David Miller in regards to this.

I am also now defaulting to always leaving the first buffer unmapped on any
packet and then unmapping it after we read the EOP descriptor.  This allows
a simplification of the path with less branching.

Instead of counting packets received the code was changed some time ago to
track the number of buffers received.  This leads to inaccurate counting
when you compare numbers of packets received by the hardware versus what is
tracked by the software.  To correct this I am revising things so that the
append_cnt value for RSC accurately tracks the number of frames received.

Subject: ixgbe: Address fact that RSC was not setting GSO size for incoming
 frames

This patch is meant to address the fact that RSC has not been setting the
gso_size value on the skb.  As a result performance on lossy TCP
connections was negatively impacted.  This change resolves the issue by
setting gso_size to the average size for incoming packets.

Subject: ixgbe: Let the Rx buffer allocation clear status bits instead of
 cleanup

This change makes it so that we always clear the status/error bits in the
Rx descriptor in the allocation path instead of the cleanup path.  The
advantage to this is that we spend less time modifying data.  As such we
can modify the data once and then let it go cold in the cache instead of
writing it, reading it, and then writing it again.

Subject: ixgbe: Drop the _ADV of descriptor macros since all ixgbe descriptors
 are ADV

It doesn't make much sense to differentiate between advanced and legacy
descriptors when the only descriptors that ixgbe uses are advanced
descriptors.  As such we can drop the _ADV suffix since all ixgbe
descriptors are automatically advanced.

Subject: ixgbe: Combine post-DMA processing of sk_buff fields into single
 function

This change combines a number of post-DMA Rx packet processing functions
into a single function.  The advantage of this is that it combines most of
the Rx descriptor processing into one spot so it should all be warm in the
cache.

Subject: rename dev_hw_addr_random and remove redundant second

Renamed dev_hw_addr_random to eth_hw_addr_random() to reflect that
this function only assign a random ethernet address (MAC). Removed
the second parameter (u8 *hwaddr), it's redundant since the also
given net_device already contains net_device->dev_addr.
Set it directly.

Adapt igbvf and ixgbevf to the changed function.

Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails
(which means the device got no dev_addr) handle the error and
jump to err_sw_init as already done by igbvf in similar case.

Subject: be2net: event queue re-design

v2: Fixed up the bad typecasting pointed out by David...

In the current design 8 TXQs are serviced by 1 EQ, while each RSS queue
is serviced by a separate EQ. This is being changed as follows:

- Upto 8 EQs will be used (based on the availabilty of msix vectors).
Each EQ will handle 1 RSS and 1 TX ring. The default non-RSS RX queue and
MCC queue are handled by the last EQ.

- On cards which provide support, upto 8 RSS rings will be used, instead
of the current limit of 4.

The new design allows spreading the TX multi-queue completion processing
across multiple CPUs unlike the previous design.

Subject: enic: remove assignment of random mac on enic vf

This patch removes random mac assignment on vf's. The vf's will start with
a zero mac and with upcoming support in fw/driver, a vf mac can be set
via the pf. vf's also support ndo_set_mac_address. This decision was made
based on the fact that a random mac on a vf is not really needed. And this
will reduce some of the problems with the vf's getting a new mac on
every driver load/unload (one of them being udev renaming the device on ever
load/unload and reboot).

Subject: e1000e: cleanup: use goto for common work needed by multiple exit

There are two exit points of e1000e_write_nvm_spi() which require the
nvm->ops.release() function pointer called just before exiting.
Consolidate the two duplicate pieces of common work with a goto.  With
this change, the value ret_val will need to be returned instead of 0.

In the unlikely event that e1e_wphy() returns an error, the returned error
code is not propogated to the caller of e1000_set_d3_lplu_state_ich8lan().
With this change, there is a rare possibility that ret_val might not get
set so it must be initialized.

Subject: e1000e: cleanup goto statements to exit points without common work

Per ./Documentation/CodingStyle, goto statements are acceptable for the
centralized exiting of functions when there are multiple exit points which
share common work such as cleanup.  When no common work is required for
multiple exit points, the function should just return at these exit points
instead of doing an unnecessary jump to a centralized return.  This patch
cleans up the inappropriate use of goto statements, and removes unnecessary
variables (or move to a smaller scope) where possible as a result of the
cleanups.

From d9ab70079a9730f2d748714cbe4242bc707b9eef Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Mon, 13 Feb 2012 23:29:16 +0000
Subject: sfc: Skip RX end-of-batch work on channels without an RX queue

The code in efx_process_channel() to update the RX queue after each
batch of RX completions works out as a no-op on a TX-only channel
where the RX queue structure is set to all-zeroes, but
(1) efx_channel_get_rx_queue() will BUG() if DEBUG is defined, and
(2) it's a waste of time.

Subject: sfc: Do not retry hardware probe if it schedules a reset

If efx_pci_probe_main() schedules an INVISIBLE or ALL reset (but
nothing more drastic), we retry it up to 5 times.  So far as I'm
aware, this was a workaround for bugs in Falcon A0 which were fixed
in production silicon.  Remove the retry.

Subject: sfc: Replace some literal constants with EFX_PAGE_SIZE/EFX_BUF_SIZE

The 'page size' for PCIe DMA, i.e. the alignment of boundaries at
which DMA must be broken, is 4KB.  Name this value as EFX_PAGE_SIZE
and use it in efx_max_tx_len().  Redefine EFX_BUF_SIZE as
EFX_PAGE_SIZE since its value is also a result of that requirement,
and use it in efx_init_special_buffer().

Subject: tg3: Reduce UMP event collision window

The tg3 driver needs to submit a few phy register values to the UMP
firmware each time the link state changes.  Up until now, the driver
would wait for the previous event to complete, then proceed to gather
data through a series of phy accesses.  Since phy accesses are
relatively slow, it is possible for another thread to attempt to submit
its own event while the UMP code is still construction its message.

This patch seeks to minimize the collision window as much as possible by
preloading the phy data.

Subject: tg3: Remove unused link config code

When tg3 devices are shutdown, the driver uses the
TG3_PHYFLG_IS_LOW_POWER flag to enable a static phy configuration.
Any attempt to use the link configuration variables is dead code.  This
patch removes such code.

Subject: tg3: Remove unneeded link_config.orig_... members

This patch removes the unneeded link_config.orig_* members.  When the
phy is in a low power state, the TG3_PHYFLG_IS_LOW_POWER flag solely
determines how the link is configured.  When the phy is powered back up,
it can resume using the original settings.

For the phylib case, the link configuration still needs to be saved, but
since the phylib maintains its own configuration, we can repurpose the
(unused in this case) tg3 link configuration members.

Subject: mlx4_core: fix buffer overrun

When passing MLX4_UC_STEER=1 it was translated to value 2
after mlx4_QP_ATTACH_wrapper. Therefore in new_steering_entry()
unicast steer entries were added to index 2 of array of size 2.
Fixing this bug by shift right to one position.

Subject: mlx4: fix QP tree trashing

When adding new unicast steer entry, before moving qp to state ready,
actually before calling mlx4_RST2INIT_QP_wrapper(), there were added
a lot of entries with local_qpn=0 into radix tree.
This fact impacted the get_res() function and proper functioning
of resource tracker in addition to adding trash entries into radix tree.

Subject: mlx4: add unicast steering entries to resource_tracker

Add unicast steering entries to resource tracker.
Do qp_detach also for these entries when VF doesn't shut down gracefully.
Otherwise there is leakage of these resources, since they are not tracked.

drivers/net/wireless/wl1251/boot.c:467:21:    expected unsigned int [unsigned] [assigned] [usertype] val
drivers/net/wireless/wl1251/boot.c:467:21:    got restricted __le32 [usertype] <noident>

Fix this by removing one cpu_to_le32() call in the wrong place.

The 32-bit values were not converted before writing them to the chip.
Change the wl1251_read32() and wl1251_write32() so that they always
read and write le32 values and convert to and from the CPU endianess.

The interrupt threaded handler exits immediately if the driver's state
is WL1271_STATE_OFF. As a result, the interrupt status is not read. If
the interrupt is level triggered, it will be fired again.

Fix this by disabling interrupts before setting the state to OFF.

Subject: wl12xx: cancel delayed elp work and clear flags when stopping PLT

In some cases a race condition can happen if we don't cancel any
pending ELP work before stopping PLT.  With this commit we cancel ELP
work and clear the wl->flags bitmask.  Also clean up the wl elements
after powering off.

Subject: wl12xx: move partition table definition to io.c

Up till now we only needed to access the partition table in boot.c.
But to add support for reading the MAC address from the FUSE in
testmode, we will have to change the partition in testmode.c.

Thus, we move the partition table to io.c and export it via io.h.  It
makes more sense to have it in the io part anyway.

Subject: wl12xx: read chip ID and HW PG version during probe

In order to read the MAC addresses from the fuse ROM, we need to know
the chip ID and the HW PG version.  We need to know the MAC address
during probe, because that's when we register our HW with mac80211.

To prepare for that, this patch reads the chip ID and HW PG version
during probe instead of doing it at boot time.  We power the chip on
briefly in order to do that.

Subject: wl12xx: use two MAC addresses based on the NVS or from fuse ROM

Add support for two MAC addresses.  If the NVS has a valid MAC
address, that takes precedence and we use two sequential address
starting from the one specified.

If the NVS doesn't contain a valid MAC address (ie. if it is set to
00:00:00:00:00:00), we check if the HW PG version in use has the
BD_ADDR written in the fuse ROM.  If it does, we read it and derive
the two subsequent addresses for WLAN.

During production, 3 addresses are reserved per device.  The first for
Bluetooth (burnt in the fuse ROM) and the following two for WLAN.

This patch has some code by Igal and Arik (squashed from internal
patches).

Subject: wl12xx: add testmode operation to read the BD_ADDR from Fuse ROM

Add a testmode command to retrieve the BD_ADDR that is stored in the
Fuse ROM in newer PGs.  In old PGs this operation is not supported.
The caller can then derive the MAC addresses from it.

Subject: wl12xx: remove wl1271_tx_update_filters

wl1271_tx_update_filters() is used as some workaround
to open filters while roaming on the same channel.

However, it doesn't handle roaming to a different channel,
and it might also sleep in the tx path, which is a bug.

With the new auth/assoc redesign, roaming is much simpler,
and this function is not needed anymore.

Subject: Revert "wl12xx: Change claiming of the SDIO bus"

This reverts commit 393fb560d328cc06e6a5c7b7473901ad724f82e7.

Commit b6ad726 ("mmc: core: Prevent too long response times
for suspend") fails the suspend if the mmc host can't be
claimed before suspend. As the host is claimed by us as long
as the chip is powered on, suspend will always fail.

Revert to claiming the sdio bus only when needed.

Subject: wl12xx: don't release/claim sdio on suspend/resume

Since we reverted to claiming the host only when needed,
we no longer need to release/claim the host on suspend/resume.

Subject: wl12xx: fw api change - add role_id to set_template

The set_template commands now takes the role_id as
parameter.

Usually, we'll use the vif's main role_id.
However, sometimes we'll want to use
wlvif->dev_role_id instead of wlvif->role_id,
so pass the wanted role_id as param.

Update WL127X_FW_NAME/WL128X_FW_NAME.

(This commit starts a series of fw update patches,
and changes the start() callback to return an error
in order to prevent the use of the driver during the
transition. This change will be reverted in the
last patch of series)

Subject: wl12xx: use dev_role_id for scans

Use device role for scans when the sta is not
associated.

sched_scan is used only when the sta is
not associated, and thus should use
the dev role (instead of sta role).

Subject: wl12xx: fw api change - add role_id to tsf_info

The ACX_TSF_INFO command now takes role_id as param.
change the struct accordingly, and pass the wlvif
to the wl1271_acx_tsf_info() function.

From f1d63a59635feef3481ed1972a883a5d6be7f9bb Mon Sep 17 00:00:00 2001
From: Eyal Shapira <eyal@wizery.com>
Date: Tue, 31 Jan 2012 11:57:21 +0200
Subject: wl12xx: add support for HW dynamic PS

FW now supports dynamic PS so we don't need to use mac80211 support.
FW will go to PSM after a specified timeout with no Rx/Tx traffic.
- Changed FW API to include new PS mode (AUTO_MODE) and including timeout parameter
- The default PS mode would be dynamic PS
- Default timeout is 100ms (same as it used to be in mac80211)
- Avoid using mac80211 APIs to disable/enable dynamic PS as we're not
using mac80211 PS control anymore.
- COEX is handled by the FW while in dynamic PS so removed
handling of SOFT_GEMINI

Subject: wl12xx: add dynamic_ps_timeout debugfs file

Enable read/write of dynamic_ps_timeout which controls the timeout
of the dynamic PS implemented in the FW.
dynamic_ps_timeout is the timeout (in msec) until going back to PS
when there's no Rx/Tx

Subject: wl12xx: enable/disable BET with AUTO_PS/ACTIVE

While the FW with dynamic PS controls BET when going to PSM and back
internally within the FW, there's still a need to enable it from the driver
at least once (so enable on every entry to AUTO_PS)
and disable it once we explicitly go back to STATION_ACTIVE_MODE.
BET isn't relevant for 5GHz

Subject: wl12xx: change WLVIF_FLAG_PSM name and remove
 WLVIF_FLAG_PSM_REQUESTED

WLVIF_FLAG_PSM turned to WLVIF_FLAG_IN_AUTO_PS which
marks that this vif is in AUTO PS.

WLVIF_FLAG_PSM_REQUESTED is not required as mac80211
calls op_config with CONF_PS after association.

wl12xx_config_vif() handling of CONF_PS was simplified
and cleaned up.

it to the fw.

Subject: wl12xx: add suspend_listen_interval debugfs file

Add read/write to suspend_dtim_interval file which
controls the number of DTIM periods between wakeups
while the host is suspended.
The value while the host is resumed is controlled
by the file dtim_interval which existed previously.

Subject: wl12xx: add forced_ps mode

For certain WiFi certification tests forcing PS
is necessary. Since DPS is now enabled in the FW
and this can't be achieved by using netlatency
this required a new config option.

Subject: wl12xx: consider encryption and QoS in auto arp template

When configuring the arp response template,
and encryption is enabled, we should add some
space and set the protected flag bit in the fc.

In order to track the encryption type, set
wlvif->encryption_type when setting an encryption key,
and reconfigure the arp response. Clear this field on
wl1271_join, as keys have to be re-configured
anyway after a join command.

Similarly, track whether QoS is configured.

Subject: wl12xx: Revert "wl12xx: disable auto-arp"

This reverts commit e5e2f24b3eec67a7a35d43654a997f98ca21aff2.

The encryption consideration on auto-arp configuration,
along with a fw fix, seem to resolve the crashes that
occured when auto-arp was enabled, so we can re-enable it now.

the join.

Subject: wl12xx: declare support for hw scan while idle

By allowing hw scan while idle, we no longer
need the redundant ROC/CROC that are done
on idle off/on, which helps simplifying the
state machine of the driver.

This way, we can also allow scanning while
there is an ongoing sched scan (otherwise,
we won't be able to ROC on idle-off)

Subject: wl12xx: don't fail on AP scan

AP role uses its own role_id for scans, so there's
no reason to fail the scan if dev_role_id is invalid.

Subject: wl12xx: use split scan for normal scan

Split scan allows the FW to schedule other activities
during a scan which may be a long operation. This is
achieved by setting a trigger TID to ANY_TID and a scan
trigger timeout other than 0. The default one is set to 50ms.

Subject: wl12xx: dynamically change fw according to number of active roles

wl12xx uses different fw for single-role and multi-role
scenarios (due to lack of space, some of the fw advanced
features are disabled in the multi-role fw).

Add checks on add_interfae and remove_interface in order
to determine whether a fw switch is needed (and initiate
recovery in this case).

Enter forced psm when changing fw, in order to make the
sta a bit more disconnection-persistent.
(DPM doesn't know about the incoming recovery, so it
won't enter psm by itself)

Subject: wl12xx: remove some dead code in wl1271_plt_init()

"ret" has already been checked at this point, and we don't need to check
it again.  This was left around from a previous patch 49d750ca14
"wl12xx: 1281/1283 support - New radio structs and functions".

Subject: bnx2x: consistent statistics after internal driver reload

Currently bnx2x statistics are reset by inner driver reload, e.g. by MTU
change. This patch fixes this issue - from now on statistics should only
be reset upon device closure.
Thanks to Michal Schmidt <mschmidt@redhat.com> for his initial patch
regarding this issue.

From f2cedb63df14342ad40a8b5b324fc5d94a60b665 Mon Sep 17 00:00:00 2001
From: Danny Kukawka <danny.kukawka@bisect.de>
Date: Wed, 15 Feb 2012 06:45:39 +0000
Subject: net: replace random_ether_addr() with eth_hw_addr_random()

Replace usage of random_ether_addr() with eth_hw_addr_random()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Change the trivial cases.

v2: adapt to renamed eth_hw_addr_random()

From 7ce5d222190cb3ce3ae88bafde7c4fa52a5103e0 Mon Sep 17 00:00:00 2001
From: Danny Kukawka <danny.kukawka@bisect.de>
Date: Wed, 15 Feb 2012 06:45:40 +0000
Subject: net: use eth_hw_addr_random() and reset addr_assign_type

Use eth_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

v2: adapt to renamed eth_hw_addr_random()

Subject: sfc: Add support for configuring RX unicast/multicast default filters

On Siena all received packets that don't match a more specific filter
will match the unicast or multicast default filter.  Currently we
leave these set to the default values (RSS with base queue number of
0).  Allow them to be reconfigured to select a single RX queue.

These default filters are programmed through the FILTER_CTL register,
but we represent them internally as an additional table of size 2.

Subject: sfc: Add support for TX MAC filters

On Siena each TX queue can be configured to send only packets for
which there is a TX MAC filter that matches the source MAC address,
queue ID, and optionally VID.  This will be used to implement the
'spoofchk' feature for SR-IOV virtual functions.

Subject: sfc: Correct MAC filter bitfield definitions

The RMFT_DEST_MAC and TMFT_SRC_MAC register fields were previously
documented as 44 bits wide, whereas a MAC address has 48 bits.
Thankfully the hardware uses the correct width and the driver has
used separate definitions that divide each of these into 32-bit and
16-bit fields.

Fix the initial definitions for these fields and rewrite the latter
definitions to use them.

Subject: sfc: Leave interrupts and event queues enabled whenever we can

When SR-IOV is enabled we may receive FLR (Function-Level Reset)
events, associated queue flush events and requests from VF drivers at
any time.  Therefore we need to keep event queues and interrupts
enabled whenever possible.

Currently we stop interrupt-driven event processing before flushing RX
and TX queues; efx_nic_flush_queues() then polls event queues for
flush events and discards any others it finds.  Change it to work with
the regular event handling functions.

Currently efx_start_channel() fills RX queues synchronously when a
device is brought up.  This could now race with NAPI, so change it to
send fill events.

This was almost entirely written by Steve Hodgson, formerly
shodgson@solarflare.com.

Subject: sfc: Generalise event generation to cover VF-owned event queues

For SR-IOV we will need to send events to event queues that belong to
VFs serviced by other drivers.  Change the parameters of
efx_generate_event() to allow this and declare it extern.

While we're at it, remove the existing declaration under the wrong
name efx_nic_generate_event().

From a606f4325dca6950996abbae452d33f2af095f39 Mon Sep 17 00:00:00 2001
From: Steve Hodgson <shodgson@solarflare.com>
Date: Mon, 23 May 2011 12:18:45 +0100
Subject: sfc: Disable flow control during flushes

The TX DMA engine issues upstream read requests when there is room in
the TX FIFO for the completion. However, the fetches for the rest of
the packet might be delayed by any back pressure.  Since a flush must
wait for an EOP, the entire flush may be delayed by back pressure.

Mitigate this by disabling flow control before the flushes are
started.  Since PF and VF flushes run in parallel introduce
fc_disable, a reference count of the number of flushes outstanding.

The same principle could be applied to Falcon, but that
would bring with it its own testing.

Subject: sfc: Add support for 'extra' channel types

Abstract some of the channel operations to allow for 'extra'
channels that do not have RX or TX queues.

- Try to assign a channel to each extra channel type that is enabled
  for the NIC, but gracefully degrade if we can't allocate sufficient
  MSI-X vectors
- Allow each extra channel type to generate its own channel name
- Allow channel types to disable reallocation and reinitialisation
  of their channels

Subject: sfc: Pass NIC structure into efx_wanted_parallelism()

This lets us identify the NIC affected in case of failure, and
will be necessary to adjust for SR-IOV constraints.

Subject: sfc: Allocate SRAM between buffer table and descriptor caches at init
 time

Each port has a block of 64-bit SRAM that is divided between buffer
table and descriptor cache regions at initialisation time.  Currently
we use a fixed allocation, but it needs to be changed to support
larger numbers of queues.

From cd2d5b529cdb9bd274f3e4bc68d37d4d63b7f383 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Tue, 14 Feb 2012 00:48:07 +0000
Subject: sfc: Add SR-IOV back-end support for SFC9000 family

On the SFC9000 family, each port has 1024 Virtual Interfaces (VIs),
each with an RX queue, a TX queue, an event queue and a mailbox
register.  These may be assigned to up to 127 SR-IOV virtual functions
per port, with up to 64 VIs per VF.

We allocate an extra channel (IRQ and event queue only) to receive
requests from VF drivers.

There is a per-port limit of 4 concurrent RX queue flushes, and queue
flushes may be initiated by the MC in response to a Function Level
Reset (FLR) of a VF.  Therefore, when SR-IOV is in use, we submit all
flush requests via the MC.

The RSS indirection table is shared with VFs, so the number of RX
queues used in the PF is limited to the number of VIs per VF.

This is almost entirely the work of Steve Hodgson, formerly
shodgson@solarflare.com.

+/**
+ * DOC: Virtual Function Driver Interface
+ *
+ * This file contains software structures used to form a two way
+ * communication channel between the VF driver and the PF driver,
+ * named Virtual Function Driver Interface (VFDI).
+ *
+ * For the purposes of VFDI, a page is a memory region with size and
+ * alignment of 4K.  All addresses are DMA addresses to be used within
+ * the domain of the relevant VF.
+ *
+ * The only hardware-defined channels for a VF driver to communicate
+ * with the PF driver are the event mailboxes (%FR_CZ_USR_EV
+ * registers).  Writing to these registers generates an event with
+ * EV_CODE = EV_CODE_USR_EV, USER_QID set to the index of the mailbox
+ * and USER_EV_REG_VALUE set to the value written.  The PF driver may
+ * direct or disable delivery of these events by setting
+ * %FR_CZ_USR_EV_CFG.
+ *
+ * The PF driver can send arbitrary events to arbitrary event queues.
+ * However, for consistency, VFDI events from the PF are defined to
+ * follow the same form and be sent to the first event queue assigned
+ * to the VF while that queue is enabled by the VF driver.
+ *
+ * The general form of the variable bits of VFDI events is:
+ *
+ *       0             16                       24   31
+ *      | DATA        | TYPE                   | SEQ   |
+ *
+ * SEQ is a sequence number which should be incremented by 1 (modulo
+ * 256) for each event.  The sequence numbers used in each direction
+ * are independent.
+ *
+ * The VF submits requests of type &struct vfdi_req by sending the
+ * address of the request (ADDR) in a series of 4 events:
+ *
+ *       0             16                       24   31
+ *      | ADDR[0:15]  | VFDI_EV_TYPE_REQ_WORD0 | SEQ   |
+ *      | ADDR[16:31] | VFDI_EV_TYPE_REQ_WORD1 | SEQ+1 |
+ *      | ADDR[32:47] | VFDI_EV_TYPE_REQ_WORD2 | SEQ+2 |
+ *      | ADDR[48:63] | VFDI_EV_TYPE_REQ_WORD3 | SEQ+3 |
+ *
+ * The address must be page-aligned.  After receiving such a valid
+ * series of events, the PF driver will attempt to read the request
+ * and write a response to the same address.  In case of an invalid
+ * sequence of events or a DMA error, there will be no response.
+ *
+ * The VF driver may request that the PF driver writes status
+ * information into its domain asynchronously.  After writing the
+ * status, the PF driver will send an event of the form:
+ *
+ *       0             16                       24   31
+ *      | reserved    | VFDI_EV_TYPE_STATUS    | SEQ   |
+ *
+ * In case the VF must be reset for any reason, the PF driver will
+ * send an event of the form:
+ *
+ *       0             16                       24   31
+ *      | reserved    | VFDI_EV_TYPE_RESET     | SEQ   |
+ *
+ * It is then the responsibility of the VF driver to request
+ * reinitialisation of its queues.

Subject: net: sh_eth: add the value of tsu to the SH7757's GETHER

The SH7757's GETHER has TSU registers. So, this patch adds the value
of ".tsu = 1" in the sh_eth_cpu_data.

Subject: net: sh_eth: change the condition of initialization

The SH7757 has 2 Fast Ethernet and 2 Gigabit Ethernet, and the first
Gigabit channel needs the initialization. So, this patch adds the
parameter of "needs_init", and if the sh_eth_plat_data is set it
to 1, the driver will initialize the channel.

Subject: net: sh_eth: modify a condition of ioremap for TSU

If the controller has TSU, the each channel needs TSU registers.
This patch also fixes the iounmap condition in the sh_eth_drv_remove().

Subject: net: sh_eth: add support for VLAN tag filtering

Some controllers have TSU. It can register one VLAN tag, and it can
filter other VLAN tag by hardware.
If vlan_rx_add_vid() is called twice or more, the driver will disable
the filtering.

From 6c55f5ed3a23ba60a0e7809a39ad7361ae00a764 Mon Sep 17 00:00:00 2001
From: Amit Beka <amit.beka@intel.com>
Date: Wed, 25 Jan 2012 13:30:27 +0200
Subject: iwlwifi: testmode new indirect RW API

Replaced the old SRAM and periphery indirect access functions
with a unified indirect memory access functions. These include
new IWL_TM_CMDs for buffer read/write/dump which replace the
SRAM read/dump commands, but the API for IWL_TM_CMD_INDIRECT_REG
read/write will now not be supported (returns error).

This also handles writing to periphery registers in 1-3 bytes.

Requires the corresponding patch in the library for the API change.

From cdfef6c224f9490215cadd91b34c579757a6e59d Mon Sep 17 00:00:00 2001
From: Amit Beka <amit.beka@intel.com>
Date: Tue, 31 Jan 2012 15:30:39 +0200
Subject: iwlwifi: added reply data to testmode HCMD send

The testmode command for host command send now replies
with a nl80211 message and the response it recieved from
the device.

This does not change the API directly, but adds a reply
to the testmode call.

Subject: iwlwifi: trace debug messages

Make iwlwifi record all debug messages into
tracing, even if debug_level is not enabled.
Due to the lack of APIs, the debug messages
are now recorded up to a max length of 100,
the only one above that is the RXON which is
not needed if you trace the commands as well
as it only dumps the command contents.

Subject: iwlwifi: move workqueue to priv

In order to separate the different parts of the
driver better, we are reducing the shared data.
This moves the workqueue to "priv", and removes
it from the transport. To do this, simply use
schedule_work() in the transport.

Subject: iwlwifi: give PCIe its own lock

Instead of using a global lock, the PCIe transport
can use an own lock for its IRQ. This will make it
possible to not disable IRQs for the shared lock.
The lock is currently used throughout the code but
this can be improved even further by splitting up
the locking for the queues.

Subject: iwlwifi: kill iwl_down and s/__iwl_down/iwl_down

iwl_down was just a wrapper around __iwl_down which was called from
one place only. Replace it to direct call to iwl_down. Add lockdep
warning in iwl_down to ensure it was called with the mutex held.

Subject: iwlwifi: send testmode hcmd reply with rx header

When a host command is sent through testmode, the whole
reply (including rx header) is returned to the user, and not
only the payload of the rx.
Before this commit the length was buggy - the reply contained 4 bytes
after the end of the payload.

Subject: iwlwifi: enable receiving beacons when not associated

If the firmware implements beacon filtering,
beacons are filtered when not associated. This causes
association failures on channels marked passive.

Enabling this flag indicates to the firmware to allow
the beacons to pass through when not associated only.

Set addr_assign_type correctly to NET_ADDR_RANDOM in case
a random MAC address was generated and assigned to the netdevice.

Fix error handling in atl1c_probe(). If atl1c_read_mac_addr()
couldn't get the hw mac address, and a random mac address get
set return the error code. Don't go to err_eeprom in
atl1c_probe(), use the generated MAC address in this case.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

 module_platform_driver

Follow commit db62f684. Convert the driver to use the
module_platform_driver() macro which makes the code a bit smaller and
simpler.

Subject: cisco/enic: use eth_hw_addr_random() instead of random_ether_addr()

Use dev_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

v3: adapt to net-next
v2: use bitops, adapt to eth_hw_addr_random(), add a comment

Subject: enic: Fix ndo_set_vf_mac and ndo_set_vf_port to set/get the sriov
 vf's mac

This patch fixes the ndo_set_vf_mac netdev op to set the sriov vf mac
in adapter using the new fw devcmd CMD_SET_MAC_ADDR. During port profile
associate the pf driver gets the vf mac using CMD_GET_MAC_ADDR.

Subject: enic: Add support for fw init command on sriov vf's

This patch fixes enic_probe to do a fw init devcmd for sriov vfs.
This enables vf driver in the guest to get into adapter init state without
having to explicitly issue an init fw cmd with portprofile info. But a
successful init on the vf will require the port profile information to be
pre-provisioned by the hypervisor via the pf

Subject: use FW 7.2.16

The patch integrates FW 7.2.16 HSI and implements driver
part of GRO flow.

FW 7.2.16 adds the ability to aggregate packets for GRO
(and not just LRO) and also fixes some bugs.

1. Added new aggregation mode: GRO. In this mode packets are aggregated
   such that the original packets can be reconstructed by the OS.
2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32.
3. Adding the FCoE statistics structures to the BNX2X HSI.
4. Wrong configuration of TX HW input buffer size may cause theoretical
   performance effect. Performed configuration fix.
5. FCOE - Arrival of packets beyond task IO size can lead to crash.
   Fix firmware data-in flow.
6. iSCSI - In rare cases of on-chip termination the graceful termination
   timer hangs, and the termination doesn't complete. Firmware fix to MSL
   timer tolerance.
7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles
   open at the initiator side. Firmware implementation corrected to drop
   FIN received out-of-order or with isles still open.
8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes
   from the beginning of iSCSI PDU. Firmware implementation corrected
   to support arbitrary aligned retransmissions.
9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic
   might lead to crash. Firmware fix to relevant flow.

Subject: bnx2x: add gro_check

The patch provides workaround for BUG in FW 7.2.16,
which in GRO mode may miscalculate buffer and
place on SGE one frag less than it could.
It may happen only for some MTUs, we mark these MTUs
with gro_check flag during device initialization or
MTU change.

Next FW should include fix for the issue and the
patch could be reverted.

eth_mac_addr(). Additional advantage: eth_mac_addr() already
checks if the given address is valid.

Subject: brcm80211: smac: remove redundant assignments from
 txpwrctrl_pwr_setup_nphy

The function wlc_phy_txpwrctrl_pwr_setup_nphy() does assign a local
variable target_pwr_qtrdbm in several code paths, but in the end all
code paths are coming to an assignment of that variable which does
override all previous. So those early and redundant assignments have
been removed.

Subject: brcm80211: smac: fix endless retry of A-MPDU transmissions

The A-MPDU code checked against a retry limit, but it was using
the wrong variable to do so. This patch fixes this to assure
proper retry mechanism.

This problem had a side-effect causing the mac80211 flush callback
to remain waiting forever as well. That side effect has been fixed
by commit by Stanislaw Gruszka:

commit f96b08a7e6f69c0f0a576554df3df5b1b519c479
Date:   Tue Jan 17 12:38:50 2012 +0100

The fields bus_priv and drvr are defined as void pointer. It is
preferred to have specific types for compiler type checking. To
prepare for other bus types the bus_priv field is defined as a
union containing the sdio bus private structure reference.

Subject: brcm80211: fmac: only return success in brcmf_sdbrcm_bus_init() when
 true

The function brcmf_sdbrcm_bus_init() always returned success except for
firmware download failure. However, also when enabling SDIO function 2
is failing the function should return failure. This patch fixes that.

Subject: brcm80211: fmac: update bus state in common driver part

The bus state is updated in the sdio bus init function, but it is
better to do it when the brcmf_bus_start() function is completed
successfully. The brcmf_netdev_open() function will return -EAGAIN
until the state is updated instead of calling brcmf_bus_start() to
avoid reentering that function.

replaces them using the spin_loc_irqsave and spin_unlock_irqrestore
functions.

This patch extends the use of the brcmfmac driver with support for
chipsets with a USB host interface. The first chipsets supported are
the bcm43235, bcm43236, and bcm43238 for which firmware has been
submitted.

This driver change has been successfully built for x86, x86_64,
ppc64, arm_le, and mips_be.

It has been tested successfully on x86 and x86_64.

Subject: brcm80211: fmac: make sdio firmware filename specific

The sdio driver part uses firmware name brcmfmac.bin. With addition
of usb this name is too generic. This patch renames the filename
to brcmfmac-sdio.bin.

Subject: rtlwifi: rtl8192se firmware load can overflow target buffer

Define RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE which represents the
maximimum possible firmware file size. Use it in the definition
of the buffer which receives the firmware file data.

Set RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE closer to the actual size of
the firmware file, e.g., 90000 (down from hard coded 164000). The current
size of rtlwifi/rtl8192sefw.bin is 88856.

Set max_fw_size to RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE for the size limit
check. Fix the error case where max_fw_size is not cleared if the size
limit check fails.

Subject: iwlegacy: dump stack when fail to gain access to the device

Print dump stack when the device is not responding. This should give
some more clue about the reason of failure. Also change the message we
print, since "MAC in deep sleep" is kinda confusing.

On the way add unlikely(), as fail to gain NIC access is hmm ...
unlikely.

Subject: iwlegacy: always check if got h/w access before write

Before we write to the device register always check if
_il_grap_nic_access() was successful.

Change type return type _il_grap_nic_access() to bool, and
add likely()/unlikely() statements.

Subject: iwlegacy: cleanup/fix memory barriers

wmb(), rmb() are not needed when writel(), readl() are used as
accessors for MMIO. We use them indirectly via iowrite32(),
ioread32().

What is needed mmiowb(), for synchronizing writes coming from
different CPUs on PCIe bridge (see in patch comments). This
fortunately is not needed on x86, where mmiowb() is just
defined as compiler barrier. As iwlegacy devices are most likely
not used on anything other than x86, this is not so important
fix.

If rfkill is on il_grab_nic_access() fail and we can not write to the
various registers during stop procedure. Write to those registers
unconditionally instead.

Subject: cfg80211: restructure AP/GO mode API

The AP/GO mode API isn't very clearly defined, it
has "set beacon" and "new beacon" etc.

Modify the API to the following:
 * start AP -- all settings
 * change beacon -- new beacon data
 * stop AP -- stop AP mode operation

This also reflects in the nl80211 API, rename
the commands there correspondingly (but keep
the old names for compatibility.)

Overall, this makes it much clearer what's going
on in the API.

Kalle developed the ath6kl changes, I created
the rest of the patch.

Subject: ath5k:Remove __raw_read and __raw_write

By swithing from our __raw_read and __raw_write functions to ioread32 and iowrite32,
benchmarks on my desk with iperf went from 11MBps to 18.1MBps using the AHB bus
on an EnGenius ECB3500 running OpenWRT.

Subject: sfc: Specify that the VFDI status page has page alignment and size

This requirement was meant to be implied in the name 'status page'.
One out-of-tree VF driver allocates a buffer using the structure size
and not a full page - hence the current odd specification - but in
practice that allocation will be padded and aligned to at least 4KB.
Therefore, we can specify this and have the option to extend the
structure up to 4KB without worrying about VF drivers using odd-shaped

Subject: sfc: Correct validation of peer_page_count in
 efx_vfdi_set_status_page()

efx_vfdi_set_status_page() validates the peer page count by
calculating the size of a request containing that many addresses and
comparing that with the maximum valid request size (4KB).  The
calculation involves a multiplication that may overflow on a 32-bit
system.

We use kcalloc() to allocate memory to store the addresses; that also
does a multiplication and it does check for integer overflow, so any
values larger than 0x1fffffff will be rejected.  However, values in
the range [0x1fffffffc, 0x1fffffff] pass boh tests and result in an
attempt to allocate nearly 4GB on the heap.  This should be rejected
rather quickly as it's obviously impossible on a 32-bit system, and
indeed the maximum possible heap allocation is 32MB.  Still, let's
make absolutely sure by fixing the initial validation.

 resizing

We have a very simple way of allocating buffer table entries to
queues, which is just to take the next one available.  The extra
channels are the highest numbered channels but they need to be
allocated the lowest entries so that the traffic channels can be
allocated new entries without any collisions.

Subject: tg3: Fix link check in tg3_adjust_link

The tg3 driver tried to detect link changes by comparing the tg3 local
active_speed member with SPEED_UNKNOWN (or formerly SPEED_INVALID).
This check is not correct, since phylib will never set its speed member
to either of these two values.  The code only appeared to work because
tg3 initializes active_speed to SPEED_INVALID during tg3_init_one.  This
patch introduces a new "old_link" tg3 member and then compares the
phy_device's link member against it to detect link state changes.

tg3_phy_copper_begin() has code that configures the link
advertisements through the use of the link_config.speed and
link_config.duplex members.  The driver does not internally use these
members in this way, nor is it (currently) permitted via the ethtool
interface.  This patch removes the dead code.

Subject: tg3: Clear RECOVERY_PENDING with reset_task_cancel

If an error happens in the tx completion thread, tg3_reset_task will be
scheduled and TX_RECOVERY_PENDING will be set.  The TX_RECOVERY_PENDING
flag causes tg3_poll[_msix] to return early before doing much of its
work.  Tg3_reset_task() gets canceled when the configuration of the
device is changing, which always results in a chip reset.  When this
happens, the TX_RECOVERY_PENDING flag may be left set, which would
unnecessarily hinder tg3_poll from doing work.  This patch fixes the
problem.

Subject: tg3: Create timer helper functions

This patch seeks to clean up the timer related code.  It begins by
moving one-time timer setup code from tg3_open() to tg3_init_one().
It then creates a function that encapsulates the code needed to start
the timer.  A tg3_timer_stop() function was added for parity.  Finally,
this patch moves all the timer functions to a more suitable location.

From 504f9b5a6bb5336ad434438d0cdd61a16db80129 Mon Sep 17 00:00:00 2001
From: Danny Kukawka <danny.kukawka@bisect.de>
Date: Tue, 21 Feb 2012 02:07:49 +0000
Subject: ethernet: unify return value of .ndo_set_mac_address if address is
 invalid

Unify return value of .ndo_set_mac_address if the given address
isn't valid. Return -EADDRNOTAVAIL as eth_mac_addr() already does
if is_valid_ether_addr() fails.

Subject: mcs7830: unify return value of .ndo_set_mac_address if address is
 invalid

Unify return value of .ndo_set_mac_address if the given address
isn't valid. Return -EADDRNOTAVAIL as eth_mac_addr() already does
if is_valid_ether_addr() fails.

Subject: davinci_cpdma: Fix channel number written to teardown registers

chan->chan_num is 0..CPDMA_MAX_CHANNELS-1 for tx channels and
CPDMA_MAX_CHANNELS..2*CPDMA_MAX_CHANNELS-1 for rx channels. However,
the rx and tx teardown registers expect zero based channel numbering.

Since the upper bits of the registers are reserved, the teardown also
worked before, this patch is cleanup only.

Subject: e1000e: Support RXFCS feature flag.

This enables enabling/disabling reception of the Ethernet
FCS.  This can be useful when sniffing packets.

For e1000e, enabling RXFCS can change the default
behaviour for how the NIC handles CRC.  Disabling RXFCS
will take the NIC back to defaults, which can be configured
as part of the module options.

Subject: r8169: Support RX-ALL flag.

This allows the NIC to receive packets with bad FCS and
Runts, which can help when sniffing.

NOTE:  r8169, at least on my NIC, silently drops packets
with bad FCS instead of counting them.  It seems they are
only received in any fashion if the RxCRC flag is set
(which this patch allows).

Subject: cirrus/mac89x0: print MAC via printk format specifier

Print MAC/dev_addr via printk extended format specifier %pM instead
of custom code.

Use memcpy to set the address to dev->dev_addr in set_mac_address,
instead of mxing it up in a for loop with printing a debug msg.

Check also if the given address is valid.

Subject: e1000e: cleanup: rename e1000e_id_led_init() and call as function
 pointer

Rename e1000e_id_led_init() to e1000e_id_led_init_generic() to signify the
function is used for more than one MAC-family type.  For the ich8lan MAC
family, some MACs use the generic function and others use the function
e1000_id_led_init_pchlan().  In all cases where e1000e_id_led_init() was
called directly, change to call the function pointer to be consistent with
the driver design.

Subject: e1000e: cleanup: rename e1000e_setup_link() and call as function
 pointer

Rename e1000e_setup_link() to e1000e_setup_link_generic() to signify the
function is used for more than one MAC-family type.  The 82571-family has
a custom setup_link function which also calls the generic function.  The
ich8lan-family has a custom function which should just be called via the
function pointer.  The 80003es2lan-family just uses the generic function.

Rename e1000e_reload_nvm() to e1000e_reload_nvm_generic() to signify the
function is used for more than one MAC-family type, and set and use it as a
MAC ops function pointer to be consistent with the driver design.

Subject: mlx4_en: dont change mac_header on xmit

A driver xmit function is not allowed to change skb without special
care.

mlx4_en_xmit() should not call skb_reset_mac_header() and instead should
use skb->data to access ethernet header.

This removes a dumb test : if (ethh && ethh->h_dest)

Also remove this slow mlx4_en_mac_to_u64() call, we can use
get_unaligned() to get faster code.

Subject: ath6kl: Add unicast mgmt frame buffering

PS buffering of unicast Action frames that are sent in a context
of a BSS. In AP mode when the recepient station goes to powersave
and PS_POLL flag is not set, we would buffer the frames. Send out
unicast mgmt bufferred frame when PS_POLL is received.

This fixes a bug in P2P GO behavior when sending a GO Discoverability
Request to a client that is in sleep mode.

Subject: ath6kl: assign Tx packet drop threshold per endpoint based on AC
 priority

Tx packets will begin to drop when there are multiple traffic priorities
and the current traffic is not the highest priority and the remaining
cookies drop below a certain number, which is fixed for all AC. It is
possilbe that lower priority AC have more traffic which will consume
more cookies and lock out higher priority AC from having any. Assign
each endpoint (AC) with a different Tx-packet-drop threshold so lower
priority AC is more likely to drop packets and the cookies become more
available to higher priority AC.

params, remove this bogus check.

Subject: ath9k_hw: remove duplicate initvals

Comparing SHA1 checksums of the initval tables has shown that there are many
tables that are 100% identical.

iniBank{0,1,2,3,7} and iniBB_RfGain are shared by AR5416, AR913x, AR9160
iniBank6 is shared between AR5416 and AR9160
iniBank6TPC is shared between AR913x and AR9160

iniPcieSerdes is the same for all AR9002 based devices

The CCK FIR coefficients are shared between AR9271 and AR9287

Getting rid of those duplicates saves about 7.5k uncompressed (on MIPS).

For AR9003 and later there are some duplicates as well, but I've decided to
leave them in for now, as the initvals for those chips are still actively
maintained by QCA.

Subject: ath9k: Merge wiphy and misc debugfs files

This patch merges the 'wiphy' and 'misc' debugfs files
and consolidates the information.

Information about the current channel and other HT parameters
can be obtained from both mac80211 and iw. Remove such
redundant data.

The reset statistics have been removed, they will be re-added in
a subsequent patch (in a new debugfs file).

Subject: ath9k: Initialize NF values properly

Using AR_SREV_* macros for setting up the chip-specific NF
values will make adding support for new chips hard. Use separate
macros for each chip. Currently, AR9462 has the same value for
all NF limits.

Subject: ath9k: Cleanup MCI init/deinit routines

This patch simplifies the buffer allocation functions
for MCI and removes unneeded memset calls. Also, a couple
of unused variables are removed and a memory leak in DMA
allocation is fixed.

From: Stanislav Yakovlev <stas.yakovlev@gmail.com>
Date: Thu, 23 Feb 2012 17:31:24 -0500
Subject: net/wireless: ipw2x00: Use IW_HANDLER macro from linux/wireless.h

Use IW_HANDLER macro in ipw2100.c to declare wireless handlers.

Note: ipw2200.c already uses it.

Subject: brcm80211: fmac: fix a couple checking after dereference bugs

There were two dereferencing before checking for NULL static checker
complaints in this new file.  The list cursor is never NULL so that
check can be removed.  I moved the other dereference after the check.

Subject: iwlwifi: move content of iwl_probe to post fetch_fw

This will allow to have different behavior depending on the fw.
Different fw APIs require completely different implementation
of the mac80211 APIs. Each of these implementations is called an
op_mode.

The current op_mode is called DVM which states for dual virtual MAC.

Subject: iwlwifi: move uCode flags handling to op_mode

The uCode flags modification is op_mode dependent
since the P2P config is an op-mode config.

This also fixes P2P enabling: due to the uCode
loading code shuffle moving the SKU check before
the EEPROM was read it was always false and would
always disable PAN/P2P.

Subject: iwlwifi: introducing the drv object's flows

Fetch the fw and spawn the op_mode. The op_mode that we need
to fetch is determined from the fw file.
Since the fw is fetched very early in the init flow, we can
determine what op_mode to spawn.

+ * 6) iwl_drv_start fetches the fw ASYNC, iwl_ucode_callback

Subject: iwlwifi: rename iwl_remove to iwl_op_mode_dvm_stop

iwl_remove stops the wifi flows, so rename.
Moreover, we can possibly stop the wifi flows even if the driver
is statically compiled in the kernel, so remove the __devexit pragma.

Subject: iwlwifi: virtualize the op_mode

Define the op_mode as an interface with its ops. All the functions
of the op_mode are "private", but its ops is made public in
iwl-op-mode.h.
The drv object starts the op_mode by using the start function in the
public ops.

Subject: iwlwifi: virtualize op_mode's free skb

This handler allows the transport layer to free an skb from the
op_mode. This can happen when the driver is stopped while Tx
packets are pending in the transport layer.

-/**
- * DOC: Bus layer - role and goal
- *
- * iwl-bus.h defines the API to the bus layer of the iwlwifi driver.
- * The bus layer is responsible for doing very basic bus operations that are
- * listed in the iwl_bus_ops structure.
- * The bus layer registers to the bus driver, advertises the supported HW and
- * gets notifications about enumeration, suspend, resume.
- * For the moment, the bus layer is not a linux kernel module as itself, and
- * the module_init function of the driver must call the bus specific
- * registration functions. These functions are listed at the end of this file.
- * For the moment, there is only one implementation of this interface: PCI-e.
- * This implementation is iwl-pci.c
- */
-
-/**
- * DOC: encapsulation and type safety
- *
- * The iwl_bus describes the data that is shared amongst all the bus layer
- * implementations. This data is visible to other layers. Data in the bus
- * specific area is not visible outside the bus specific implementation.
- * iwl_bus holds a pointer to iwl_shared which holds pointer to all the other
- * layers of the driver (iwl_priv, iwl_trans). In fact, this is the way to go
- * when the transport layer needs to call a function of another layer.
- *
- * In order to achieve encapsulation, iwl_priv cannot be dereferenced from the
- * bus layer. Type safety is still kept since functions that gets iwl_priv gets
- * a typed pointer (as opposed to void *).
- */
-
-/**
- * DOC: probe flow
- *
- * The module_init calls the bus specific registration function. The
- * registration to the bus layer will trigger an enumeration of the bus which
- * will call the bus specific probe function.
- * The first thing this function must do is to allocate the memory needed by
- * iwl_bus + the bus_specific data.
- * Once the bus specific probe function has configured the hardware, it
- * chooses the appropriate transport layer and calls iwl_probe that will run
- * the bus independent probe flow.
- *
- * Note: The bus specific code must set the following data in iwl_bus before it
- *       calls iwl_probe:

- *	* bus->irq
- *	* bus->ops

Subject: ath6kl: Make sure to allocate rx buffers after the endpoint
 connection

Rx buffers should be allocated for control and best effort endpoints only
after the enpoints connection is esablished. But this is done before the
endpoint connection is complete, we don't even the control and BE endpoints
that time. Move the buffer allocation after endpoint connection is over,
after ath6kl_init_hw_start(). Found in review, never seen any real issue
with this.

Subject: ath6kl: Make foreground scan a deterministic one

This makes the device get into scan state as soon as a
scan request is received, instead of blocking the scan
request till the traffic comes down. It is  necessary
for the deterministic foreground scan particularly when
having multiple vif operating where, if the scan is non-
deterministic, scan on one interface will not start
as long as there are traffic on the other interface. This
change passes 50 msec as foreground scan interval to fix this.

Subject: ath6kl: Lower SDIO pad drive strength for hw2.1.1 board

Without this change, SDIO shuts down due to CRC error during
data communication to the firmware in some of the platform.
for example, scan request issued to the firmware doesn't
return scan completed events and cause the socket interface
to always return -16 (device busy).

SDIO pad drive strength should be reduced for hw2.1.1 board
to avoid such errors.

Subject: wl12xx: set the ELP entry delay to the FW dyn-ps timeout

With PSM handled in FW, the checks in wl1271_elp_work() are always true.
Thus during active traffic we constantly enter and exit ELP (many times
per second). As each ELP exit takes ~10ms, this can have an adverse
effect on throughput and interactivity.
Set the ELP timeout to the dyn-ps timeout. This period is longer and
avoids the above problem. It also makes sense to stay out of ELP while
we are awake on the network, to minimize delays in Tx/Rx. The same thing
was done by the mac80211 dynamic-ps mechanism before the FW DPS changes.

Subject: wl12xx: reset link Tx queues when freeing it

Before, the link was first freed (invalidating it in the map), and later
on vif removal, all valid wlvif-related links were reset. Since these
links were already invalid, we failed to reset them.
The bug was made worse by op_stop, which set the tx_queue_count to 0
arbitrarily. This resulted in a negative tx_queue_count in some scenarios.

Fix this by resetting the Tx-queues of a link when freeing it. Add a
WARN_ON and reset all link Tx-queues in op_stop, to avoid a negative
tx_queue_count.

[changed WARN_ON to WARN_ON_ONCE -- Luca]

Subject: wl12xx: avoid starving the system hlid

Re-factor the Tx scheduler so that the system_hlid is taken into account
before restarting an iteration over the wlvifs. Previously this
hlid had a lower priority and would starve if some wlvif had many
packets.
In addition avoid iterating over wlvifs past last_wlvif when performing
the a second pass. If we had packets in those wlvifs they would have
been found earlier.

Subject: zd1211rw: wait between setting hash table and powering radio on

I am running Debian testing kernel 3.1.0-1-amd64, using a 079b:0062 Sagem
XG-76NA 802.11bg stick.

Upon zd1211rw interface
bringup (ifconfig wlan0 up) I get the following timeout:

[  950.330573] zd1211rw 1-3:1.0: phy2
[  955.108510] zd1211rw 1-3:1.0: firmware version 4725
[  955.148532] zd1211rw 1-3:1.0: zd1211b chip 079b:0062 v4810 high 00-19-70
AL2230_RF pa0 g--NS
[snip]
[  955.204072] zd1211rw 1-3:1.0: error ioread32(CR_REG1): -110

A second ifconfig wlan0 up brings the interface up without problems.

After a bit more debugging, the call trace is the following:

[10241.028130] zd1211rw 1-3:1.0: zd_chip_lock_phy_regs: error
ioread32(CR_REG1): -110
[10241.028140] zd1211rw 1-3:1.0: zd_switch_radio_on: failed to lock PHY regs
[10241.028148] zd1211rw 1-3:1.0: zd_op_start: failed to set radio on

Adding a 10 milliseconds delay between the call to set_mc_hash() and
zd_chip_switch_radio_on() allows successful interface bringups in all
cases and matches what the vendor driver did.

From 02f2f1a951f87644166926862ec32fb13511e2f3 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 27 Feb 2012 12:18:30 +0100
Subject: mac80211: handle non-bufferable MMPDUs correctly

This renames the IEEE80211_TX_CTL_POLL_RESPONSE
TX flag to IEEE80211_TX_CTL_NO_PS_BUFFER and also
uses it for non-bufferable MMPDUs (all MMPDUs but
deauth, disassoc and action frames.)

Previously, mac80211 would let the MMPDU through
but not set the flag so drivers supporting some
hardware aids for avoiding the PS races would
then reject the frame.

Remove the enum il_calib. It defined one identifier: IL_CALIB_MAX.
Remove the function il4965_calib_free_results. It was doing nothing
because IL_CALIB_MAX is zero. Next, remove calib_results from the
il_priv structure and also remove the associated return
type/struct il_calib_result.

Subject: ath9k: decouple RX error checking for DFS

Previous RX error checking was done exclusive-or for different error
types and caused DFS pulse events to be dropped when other error
flags (e.g. CRC) were set simultaneously.

This patch decouples PHY error processing from other types and ensures
that all pulses detected by HW are accounted by the pattern detector.

Subject: ath6kl: Refactor ath6kl_wmi_control_rx()

Split the wmi event processing into the one which needs to be
vif specific and the reset. This is a step towards avoiding
the need for wiphy and a netdev registration before getting
any message from firmware.

Subject: ath6kl: Skip vif index validation in ath6kl_rx() for wmi events

When the wmi event is vif specific, the validation of vif index
is taken care in ath6kl_wmi_proc_events_iface(). This also avoids
the need for a netdev to be registered while receiving initial events
like "target_ready" and "regulatory domain".

Subject: ath6kl: Defer wiphy and netdev registration till the end of
 ath6kl_core_init()

This makes the wiphy and initial netdev registration the last step
in dev initialization. Apart from the fact that this looks right,
it can also be used to setup wiphy with the regulatory information
received from firmware after uploading the firmware. Also it fixes
a FIXME in ath6kl_core_init() where mac address is copied into
netdev->dev_addr, ath6kl_interface_add() takes care of this as well.

As regulatory events are processed even before the wiphy is registered,
calling regulatory_hint() at early stage should be fixed.

Subject: ath6kl: Clear the IE in firmware if not set

Remove check so that IE in firmware is cleared if not set. Without this fix, any
previously set IE will be used incorrectly in the next frame. For example,
consider the scenario where a P2P device scan is followed by a regular station
scan. The P2P IE set by the P2P scan needs to be cleared, otherwise the station
scan will contain the P2P IE.

Subject: ath6kl: add padding to firmware log records

firmware debug utility expects firmware log record size
to be 1500 bytes. This patch ensures that the
firmware record will be exactly 1500 bytes.

kvalo: remove trailing space

Subject: ath6kl: Collect residue firmware logs

Collect residue firmware logs following firmware assert.
Firmware sends logs to host once the 1500 byte log buffer
has been filled. At time of assert, there could be residue
logs lying in the firmware. This patch pulls those residue
logs. This would give the full picture of the firmware.

Subject: e100: Support RXALL feature flag.

This allows the NIC to receive packets with bad FCS
and other errors.  Good for sniffing packets on flakey
networks.

v4:  Only flax rx-over-length errors if pkt is beyond
   maximum expected packet size, not just beyond the MTU.
   This matches the existing logic for this counter.

Subject: e1000e: use msleep instead of mdelay

The e1000_link_stall_workaround_lv() function is always called in non-
atomic context so it should use msleep instead of mdelay.  Also, remove
unnecessary #include <linux/delay.h>.

Subject: ath6kl: Fix random system lockup

The commit "ath6kl: Use a mutex_lock to avoid
race in diabling and handling irq" introduces a
state where ath6kl_sdio_irq_handler() would be waiting
to claim the sdio function for receive indefinitely
when things happen in the following order.

ath6kl_sdio_irq_handler()
	- aquires mtx_irq
	- sdio_release_host()
					ath6kl_sdio_irq_disable()
						- sdio_claim_host()
						- sleep on mtx_irq
	ath6kl_hif_intr_bh_handler()
		- (indefinitely) wait for the sdio
		  function to be released to exclusively claim
		  it again for receive operation.

Fix this by replacing the mtx_irq with an atomic
variable and a wait_queue.

kvalo: add ath6kl_sdio_is_on_irq() due to open parenthesis alignment

used in mdio_support.

In the mdio library, assert that its own flags continue to match those
in the ethtool interface.

In the mii library, use the ethtool flag definition and stop
including <linux/mdio.h>.

Subject: e100: Fix rx-over-length statistics.

The old code would += the total errors every time
stats were gathered.  Instead, keep a count of short-pkt
and long-pkt counters and then simply add them together
for the rx-over-length stat.

Subject: ixgbe: dcb: check setup_tc return codes

dcb netlink code calls setup_tc to init hardware traffic classes
to use for DCB. At some call sites the return values are not
checked for errors and in one case may return -EINVAL back to
the net/dcbnl.c caller which is expecting a u8.

This fixes some smatch hits and although failures are never
seen in practive its best to check return codes.

Subject: net: dcb: getnumtcs()/setnumtcs() should return an int

{g|s}etnumtcs() today returns a u8 that is only used by the DCB code
to verify no error occurred. Today the driver implementations return
negative error codes which end up being non-zero so the logic works
out but triggers some sparse warnings.

To fix the sparse warnings convert the return value to an int.

Subject: can: usb: PEAK-System Technik USB adapters driver core

This patch adds the core of the peak_usb driver which handles PEAK-System
Technik PCAN USB adapters. It defines the parts which are common to the
PCAN-USB adapters: can network interfaces management, network-to/from-usb
data path interface, timestamps management...

Subject: can: usb: PEAK-System Technik PCAN-USB specific part

This patch adds the specific part which handles the PCAN-USB adapter from
PEAK-System Technik (http://www.peak-system.com). The PCAN-USB adapter is
a sja1000 based, mono-channel USB 1.1 adapter compliant with CAN
specifications 2.0A (11-bit ID) and 2.0B (29-bit ID).

Subject: tg3: Fix jumbo loopback test on 5719

Loopback on 9K packet fails because the chip has a DMA limit of 4K.  The
loopback test logic uses a single BD for simplicity.  Fix it by reducing
the jumbo packet size to the DMA limit.

This changes the copyright notices on the PPP code that I developed
in the late 1990s from being copyright The Australian National
University to copyright Paul Mackerras.  I can do this as I have an
acknowledgement in writing from the Head of the Computer Science
Department at ANU (where I worked then) that ANU does not claim any
intellectual property in this code.

While I'm at it, change the copyright notice from BSD-style to
GNU GPL like the rest of the kernel.

Subject: ppp: Move ioctl definitions from if_ppp.h to new ppp-ioctl.h

This moves the definitions of the ioctls, constants and structures
relating to the ppp_generic interface to userspace out from if_ppp.h
to a new file, ppp-ioctl.h.  The new file has my copyright since I
designed and implemented the ppp_generic interface in the late 1990s.
None of the contents of this file comes from the original if_ppp.h
published by Carnegie Mellon University.

Of the remainder of if_ppp.h, only the PPP_MTU definition was being
used, and this replaces the uses of it with PPP_MRU (which is identical).
Therefore, this replaces the entire file with the single line

#include <linux/ppp-ioctl.h>

which clearly doesn't contain any CMU code.  Thus I have removed the
CMU copyright notice with its problematic advertising clause, and in
fact since it's only one trivial line I have not added any other

From 4b32da2bcf1de2b7a196a0e48389d231b4472c36 Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Sun, 4 Mar 2012 12:56:55 +0000
Subject: ppp: Replace uses of <linux/if_ppp.h> with <linux/ppp-ioctl.h>

Since all that include/linux/if_ppp.h does is #include <linux/ppp-ioctl.h>,
this replaces the occurrences of #include <linux/if_ppp.h> with
#include <linux/ppp-ioctl.h>.

It also corrects an error in Documentation/networking/l2tp.txt, where
it referenced include/linux/if_ppp.h as the source of some definitions
that are actually now defined in include/linux/if_pppol2tp.h.

From e19a82c18f0e6360ee9fd431721794eb0036c0cd Mon Sep 17 00:00:00 2001
From: Paul Gortmaker <paul.gortmaker@windriver.com>
Date: Mon, 27 Feb 2012 02:36:29 +0000
Subject: ucc_geth: separate out rx/tx ring alloc and free operations

Factor out the the existing allocation and free operations
so that they can be used individually.

This is to improve code readability, and also to prepare for
possible future changes like better error recovery and more
dynamic configuration (e.g on-the-fly resizing of the rings).

This change represents a straight up relocation of the existing
code into separate routines without changing any of the contained
code itself.  Local variables are relocated as necessary.

device role is used for scanning and sending packets

send packets before ibss creation, there is no need
to start the device on idle-off.

Subject: wl12xx: set authorized AP on sta_state notification

wl12xx currently looks for AP authorization by registering
a netdev notifier and waiting for the IF_OPER_UP notification,
which is quite cumbersome.

Use the newly introduced sta_state callback (waiting
for assoc -> auth notification) instead, in order to
simplify it.

Subject: wl12xx: avoid bug_on_recovery during fw switch

Add a flag to indicate we initiated a recovery work
on purpose, in order to avoid triggering BUG() (when
the bug_on_recovery module param was set).

Subject: mwifiex: handle auto authentication mode correctly

When authentication type is configured to NL80211_AUTHTYPE_AUTOMATIC,
driver tries to connect using open mode. The association is failed
if AP is configured in shared mode.

This patch adds code to try association using shared mode as well if
open mode association fails.

Now since we returned exact error code in association response handler
(instead of -1), corresponding changes are done in
mwifiex_process_cmdresp().

Subject: Revert "ath9k_hw: Fix false tx hung detection in AR9003 chips"

The approach of this change is flawed, as it triggers tx status processing
from more callsites, yet the chips only have one global tx status queue.
Subsequent patches will properly fix the issue that this one tried to address.

Subject: ssb: remove 5GHz antenna gain from sprom

There is no 2.4 GHz or 5GHz antenna gain stored in sprom. The sprom
just stores the gain values for antenna 1 and 2 or 1 to 4 for more
recent sprom versions. On old devices antenna 2 was used for 5 GHz wifi.

Subject: mwifiex: correct bitrates advertised to cfg80211

1. Driver and firmware do not support 22Mbps and 72Mbps bitrates.
Remove them from the rate table advertised to cfg80211.

2. First 4 rates from mwifiex_rates table are not valid for
5GHz/A band. Set correct bitrate array's index and no of rates for
ieee80211_supported_band for 5GHz band.

Subject: mwifiex: fix bug in wildcard scan handling

Currently if valid SSID list is provided in scan request, driver
performs specific SSID scan otherwise wildcard scan is chosen.

When wpa_supplicant provides valid SSID list followed by
zero-length SSID for wildcard scan, only specific SSID scan is
performed by driver. Actually driver is expected to do both type
of scanning in this case. The patch fixes this issue.

Also, use SSID list pointer provided by stack directly, instead
of copying SSID's to local structure.

Subject: b43: prevent firmware on bcm5354 from taking over wrong GPIO pins

When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent
firmware >= 478.104 it runs out of memory after a very short time in
OpenWrt after doing an active scan or any thing else where packages are
send. This was cased by a gpio misconfiguration, the firmware triggered
the GPIO pins used for buttons on some devices and that caused an other
driver (OpenWrt diag) listening for these buttons irqs to send many
messages to the user space.
This patch fixes the bug for my devices (Asus WL-520GU) and makes it
work with firmware 666.2. Now the firmware just uses LED GPIO pin
number 1 and not the button pins any more.

This is the GPIO Pin layout used on my device, see [0].
GPIO pin layout:
pin#    name    type
0       power   led
1       wlan    led
2       reset   button
3       ses     buttom

This is the nvram configuration output of "nvram show |grep gpio"

related nvram configuration:
wl0gpio2=11
wl0gpio3=11
wl0gpio0=11
wl0gpio1=0x02
reset_gpio=2

Subject: rndis_wlan: integer overflows in rndis_wlan_do_link_up_work()

If "offset" is negative then we can get past this check:
	if (offset > CONTROL_BUFFER_SIZE)
Or if we pick a very high "req_ie_len" then we can get around the check:
	if (offset + req_ie_len > CONTROL_BUFFER_SIZE)

I made "resp_ie_len" and "req_ie_len" unsigned.  I don't know if it was
intentional that they were signed in the original.

Subject: rndis_wlan: make some variables unsigned

These variables can never be less than zero because we cap them in
get_device_pmkids().  Let's make them unsigned here because it's simpler
to not have to worry about negative numbers when we read the code.

Subject: rndis_wlan: fix le16/le32_to_cpu mix up with config.beacon_period

'beacon_period' in 'struct ndis_80211_conf' is __le32 instead of __le16 so
le32_to_cpu must be used instead of le16_to_cpu.

Also correct 'beacon_interval' variables used for passing this value forward
from u16 to u32 and rename those variables 'beacon_period' This is to avoid
confusion because 'beacon_interval' is defined as __le16 at other structure,
'struct ndis_80211_fixed_ies'.

Subject: mwifiex: endian bug in mwifiex_drv_change_adhoc_chan()

In mwifiex_drv_change_adhoc_chan() we pass channel to
mwifiex_bss_ioctl_ibss_channel() which sets the high 16 bits.  This
works on little endian systems but not on big endian ones.  I've changed
mwifiex_drv_change_adhoc_chan() to use a 16 bit variable.  This matches
the other functions in the file.

I considered changing mwifiex_change_adhoc_chan() as well but it turns
out that the function isn't implemented so I just removed the
definition.

why the condition occurred.

Subject: rtlwifi: Remove extraneous value return

In usb.c, routine _rtl_usb_init_sw() always returns 0, and rtl_usb_probe()
never checks the returned value. Thus we can change _rtl_usb_init_sw() to
a void routine. In addition, remove the underscore at the beginning of the
name of the routine.

Subject: rtlwifi: rtl8192c: Prevent sleeping from invalid context in rtl8192cu

When driver rtl8192cu is used with the debug level set to 3 or greater,
the result is "sleeping function called from invalid context" due to
an rcu_read_lock() call in the DM refresh routine in driver rtl8192c.
This lock is not necessary as the USB driver does not use the struct
being protected, thus the lock is set only when a PCI interface is
active.

This bug is reported in https://bugzilla.kernel.org/show_bug.cgi?id=42775.

The usb code defines a structure for counting statistics. However,
it should use the statistics entry provided in brcmf_bus as that is
exposed to the net_device. The usb private statistics counter only
remains with counters for control packets between driver and usb
device.

Subject: brcm80211: smac: remove firmware requests from init_module syscall

As indicated in [1] on netdev mailing list drivers should not block
on the init_module() syscall. This patch defers the actual driver
registration to a workqueue so the init_module() syscall can complete
without delay.

Subject: r8169: add byte queue limit support.

Nothing fancy:
- sent bytes count is notified in the start_xmit path right before
  updating the owner bit in the hardware Tx descriptor (E. Dumazet)
- avoid useless tp->dev dereferencing in start_xmit (E. Dumazet)

Use of netdev_reset_queue is favored over proper accounting in
rtl8169_tx_clear_range since the latter would need more work for the
same result (nb: said accounting degenerates to nothing in xmit_frags).

Subject: ath6kl: Fix kernel panic while receiving fwlog during boot

"ath6kl: Defer wiphy and netdev registration till the end of ath6kl_core_init()"
causes kernel panic by accessing the unallocated debug resources during
boot time. To fix this, split the debug initialization funtion into two,
one initializes the debug resource and the other takes care of debugfs
initialization. When this issue shows up the kernel crash dump would
look like

Subject: sfc: Remove TX completions from adaptive IRQ scoring

RX and TX completions on the same event queue are generally not associated
with the same flows.  The inclusion of TX completions in the adaptive IRQ
score is more of a source of noise rather than useful feedback.  Therefore,
do not include them in the score, and adjust the default threshold scores
down.

Subject: sfc: Raise self-test timeouts

IRQ latency can be ridiculously high for various reasons, so our
current timeouts of 100 ms or 10 ms are too short.

Change the IRQ and event tests to use polling loops starting with a
delay of 1 tick and doubling that if necessary up to a maximum total
delay of approximately 1 second.

Raise the loopback packet RX timeout to 1 second.

Subject: sfc: Test all event queues in parallel

In case all event queues are broken for some reason, this means it
will only take about a second to check them all, rather than up to 32
seconds.  This may also speed up testing in the successful case.

Generate a test event on each event queue whenever the interface is
brought up, then after 1 second check that we have either handled a
test event or handled another IRQ for each event queue.

Subject: ath5k: allow AP and mesh mode to operate simultaneously

This patch allows the possibility of having the mesh point and AP to be operated
simultaneously in one single radio. Previously, mesh point fails to generate the
mesh beacon if virtual AP is created for the same radio.

Subject: rtlwifi: rtl8192ce: Fix loss of receive performance

Driver rtl8192ce when used with the RTL8188CE device would start at about
20 Mbps on a 54 Mbps connection, but quickly drop to 1 Mbps. One of the
symptoms is that the AP would need to retransmit each packet 4 of 5 times
before the driver would acknowledge it. Recovery is possible only by
unloading and reloading the driver. This problem was reported at
https://bugzilla.redhat.com/show_bug.cgi?id=770207.

The problem is due to a missing update of the gain setting.

Subject: iwlwifi: always monitor for stuck queues

If we only monitor while associated, the following
can happen:
 - we're associated, and the queue stuck check
   runs, setting the queue "touch" time to X
 - we disassociate, stopping the monitoring,
   which leaves the time set to X
 - almost 2s later, we associate, and enqueue
   a frame
 - before the frame is transmitted, we monitor
   for stuck queues, and find the time set to
   X, although it is now later than X + 2000ms,
   so we decide that the queue is stuck and
   erroneously restart the device

It happens more with P2P because there we can
go between associated/unassociated frequently.

The current code tests for FLAG_RADIO_OFF instead of FLAG_RADIO_DOWN.

Subject: iwlwifi: reduce sta_lock hold time in TX

When we TX, we hold the sta_lock for a long
time, a lot of which isn't needed. Reduce
the time we hold the lock. Note that this
doesn't really change anything as the code
is already under the other spinlock, but it
makes the code easier to read.

Subject: iwlwifi: build some station commands directly

In the powersave related functions we only need
to set a few parameters for the station command
and can otherwise leave it blank -- there's no
need to copy it from the database.

This allows us to not use the sta lock here.

Subject: iwlwifi: introduce per-queue locks

Instead of (ab)using the sta_lock, make the
transport layer lock its own TX queue data
structures with a lock per queue. This also
unifies with the cmd queue lock.

From fa23cb04b38a9950b21ee756e4419a737d496371 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>

Subject: iwlwifi: make sta lock private & BH lock

Now that the transport has its own locking,
there's no need to have the sta_lock in the
shared data. Also, it can be a BH lock as
it's not used from IRQ handlers.

Subject: iwlwifi: introduce statistics lock

The statistics are currently only half-heartedly
locked against concurrent reading & modification
so introduce a lock to really protect them.

Subject: iwlwifi: remove shared lock

Some data doesn't need protection, some of the
lock places are simply useless, and some data
can be protected with the mutex instead. Thus
the shared lock can be removed by making those
changes.

From 5c40d8603d8ed03aa851d20ad8a9155fc79a1b07 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 5 Mar 2012 11:24:28 -0800
Subject: iwlwifi: make EXIT_PENDING depend on mac80211

There's no reason to set EXIT_PENDING when we
start removing the module, as mac80211 will
cleanly shut down the device in this case.
Additionally, there's no point in rejecting
commands to the device when we're cleaning up
as that only leads to unwanted errors from
mac80211 being printed, such as
  failed to remove key (...) from hardware (-16)

Subject: iwlwifi: simplify auth/assoc flow

With mac80211 now giving us station information
(via the sta_state callback) before auth/assoc
we can get rid of tx_sync by adding the station
early for the case of managed interfaces. Keep
AP mode actions the same for now.

As we now get the BSSID early, we can also get
rid of iwl_reprogram_ap_sta().

We can still optimise the number of RXONs we
send to the device, but that can be done later.

Subject: iwlwifi: remove per-device debug level

There's no need for the per-device debug
level that we expose in debugfs since the
module parameter is writable in sysfs.

At the same time, simplify code by changing
    iwl_get_debug_level(shrd) & IWL_DL_ISR)
to
    iwl_have_debug_level(IWL_DL_ISR)

From 54708d8df355b7ecf1d25d4049336840e6107d96 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 5 Mar 2012 11:24:31 -0800
Subject: iwlwifi: remove SKU from config

There's no SKU override, we always just use
it from EEPROM. As such, we can remove it
from the config and use it in hw_param only.
Since iwl_eeprom_check_sku() really needs
to fill it in also rename that to
iwl_eeprom_init_hw_params().

Subject: iwlwifi: use valid TX/RX antenna from hw_params

It's not really a good idea to write to the
global static configuration. Use the valid
TX/RX antenna information only from the HW
params struct except in the case where the
values from the config are used to override
the values from the EEPROM.

Subject: iwlwifi: reduce IDI code ifdef

The code in the two branches of the #ifdef
is almost the same so move the common code
outside the #ifdef.

Subject: iwlwifi: clean up (wowlan) suspend flow

In the WoWLAN suspend flow, instead of accessing
registers directly, ask the transport to do the
required setup at the end of suspend. If the
transport doesn't implement this, don't tell the
stack we support WoWLAN.

When the device suspends w/o WoWLAN, mac80211
will have stopped it already, which has already
called iwl_apm_stop() via stop_hw(). Thus, it
isn't necessary to call it again in pcie_suspend
and we can simply do nothing there.

This unifies the regular and WoWLAN suspend.

Subject: iwlwifi: use ieee80211_tx_status

We currently use the _irqsafe version, but that
isn't recommended together with ieee80211_rx()
as it can cause races. If the device reports
a TX-status and RX in that order then with the
current combination mac80211 might process them
in the other order, which can cause issues with
powersaving clients.

Use ieee80211_tx_status() to avoid this race.
Since we don't want to call it with locks held,
process the frame queues later -- this is fine
as they are on the stack.

Subject: iwlwifi: pass response packet directly

When CMD_WANT_SKB is set for a (synchronous)
command, the response is passed back to the
caller which is then responsible for freeing
it. Make this more abstract with real API,
passing directly the response packet in the
new cmd.resp_pkt member and also introduce
iwl_free_resp() to free the pages -- this
way the upper layers don't have to directly
touch the page implementation.

NOTE: This breaks IDI -- the new code isn't reflected there yet!

From 48a2d66f58d2bf1818acf5ff7ed9897a9977a96e Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 5 Mar 2012 11:24:39 -0800
Subject: iwlwifi: don't pass iwl_rx_mem_buffer to upper layers

struct iwl_rx_mem_buffer implementation details
(DMA address, list pointers) that the upper
layers don't need. Introduce iwl_rx_cmd_buffer
that is passed upstream and only contains the
needed data (the page). Additionally, access
this data only via accessor functions, allowing
us to change the implementation in the future.
These accessors are rxb_addr() (as before) and
rxb_steal_page() to take ownership of the data.

Subject: iwlwifi: fix station HT parameters

My patch "iwlwifi: simplify auth/assoc flow"
caused a serious throughput degradation due
to me forgetting that there are HT settings
in the station table. To restore throughput,
set these parameters correctly when the sta
moves to assoc state.

This patch should probably be merged with
the auth/assoc redesign patch for upstream.
In that case, this paragraph should be added
to the commit log as the third paragraph
(before talking about RXON):

However, as we only get the station HT data
when the station moves into assoc state, we
also need to program this into the device
(and copy it into our database) then.

Subject: mac80211_hwsim: Add tsf to beacons, probe responses and radiotap
 header.

Generate a tsf from internal kernel clock.  Prepare the path for having
different tsf offsets on each phy.  This will be useful for testing
mesh synchronization algorithms.

Subject: ath5k: do not stop queues for full calibration

Some calibration types interfere with tx activity, but the queue stop does
not prevent that. In fact, some calibration types need tx activity to properly
function, so stopping the queues for them is counterproductive.
In some tests this patch has been shown to improve stability, especially in
AP or ad-hoc mode.

Subject: ath5k: do not re-run AGC calibration periodically

All other Atheros drivers run the AGC gain calibration and DC offset
calibration only after reset. Running them periodically has caused stability
issues on some (primarily AR2315/2413/5413/5414 based) devices, leading to
messages such as:

ath5k phy0: gain calibration timeout (2462MHz)
ath5k phy0: calibration of channel 11 failed

Subject: net/mlx4_en: Saving mem access on data path

Localized the pdev->dev, and using dma_map instead of pci_map
There are multiple map/unmap operations on data path,
optimizing those by saving redundant pointer access.
Those places were identified as hot-spots when running kernel profiling
during some benchmarks.
The fixes had most impact when testing packet rate with small packets,
reducing several % from CPU load, and in some case being the difference
between reaching wire speed or being CPU bound.

Fix sparse warnings on incompatibility between the endianess of the ctrl_flags

mlx4_wqe_ctrl_seg by changing the former to be __be32 instead of u32.

Subject: net/mlx4: fix sparse warnings on wrong type for RSS keys

The keys used for the hardware RSS topelitz hash are of type __be32
where the values provided by the driver are from array of u32,
this triggered sparse warning on incorrect type in assignment as of different base types.
Since these values are picked randomly,
the fix is to transform the key to __be32 by executing cpu_to_be_32()

The mac should be written as __be64 the gid. The warning was because
we changed the mac parameter, which is u64, by writing result of cpu_to_be64
into it. Fixing by using new variable of type __be64.

the mlx4_en module (were originally part of mlx4_en).
Their declaration remained in mlx4_en module, moving the declaration to the right location.

Subject: powerpc/44x: Add more changes for APM821XX EMAC driver

This patch includes:

  Configure EMAC PHY clock source (clock from PHY or internal clock).

  Do not advertise PHY half duplex capability as APM821XX EMAC does not support half duplex mode.

  Add changes to support configuring jumbo frame for APM821XX EMAC.

[ Fix coding style -DaveM ]

Subject: ath6kl: Add provision to define suspend policy in disconnected state.

It gives flexibility to the user to define suspend policy
when the suspend mode is set to WOW and the device is in
disconnected state at the time of suspend.

New module parameter wow_mode is added to get the choice
from the user. This parameter is valid only if the module
parameter suspend_mode is set to WOW.

To force WOW in connected state and cut power
in disconnected state:
  suspend_mode=0x3 wow_mode=0x1

To force WOW in connected state and deep sleep
in disconnected state (this is also the default wow_mode):
   suspend_mode=0x3 wow_mode=0x2

If there is no value specified to wow_mode during insmod,
deep sleep mode will be tried in the disconnected state.

Subject: ath6kl: Check wow state before sending control and data pkt

Below two scenarios are taken care in this patch which helped
to fix the firmware crash during wow suspend/resume.

* TX operation (ctrl tx and data tx) has to be controlled based
  on suspend state. i.e, with respect to WOW mode, control packets
  are allowed to send from the host until the suspend state goes
  ATH6KL_STATE_WOW and the data packets are allowed until WOW
  suspend operation starts.

* Similarly, wow resume is NOT allowed if WOW suspend is in progress.

Subject: ath6kl: Maintain the listen interval per VIF specific

Firmware has the option to support the listen interval
per vif specific. Fix this.

Listen interval can be set by the TUs or by the number
of beacons. Current code enables the user to configure
the listen interval in the unit of 'number of beacons'
using debugfs entry "listen_interval". Going forward,
we need to alter the listen interval in the unit of TUs
to get good power numbers while going to WOW suspend/resume.

Allowing the user to change the listen interval in
the unit of "number of beacons"  in debugfs and changing
listen interval in wow suspend/resume in the unit of
time (TUs) would lead us to confuse.

This patch make sures the listen interval is changed only
in the unit of time (TUs).

Subject: ath6kl: Set optimal listen intvl,bmiss,scan params while going to wow
 suspend

* In order to save the target power in WOW suspend state,
  configure the best optimal values for the below parameters,
     - listen interval.
     - beacon miss interval.
     - scan parameters.

  Default values for above attributes are reverted in
  wow resume operation.

* The default listen interval is set before the host issue
  connect request.

* New function is added to configure beacon miss count.

kvalo: minor changes to fix open parenthesis alignment

callers of ath6kl_bmi_write() are tricky and that needs to be fixed

Subject: ath6kl: add ath6kl_bmi_write_hi32()

We have a lot of 32 bit writes to the host interest area and the code
doing that is ugly. Clean that up by adding ath6kl_bmi_write_hi32().

This also fixes few checkpatch warnings.

Subject: ath9k: make MAC sample statistics optional

They're more expensive than some of the other debug options and only used
in very rare situations, so it sometimes makes sense to disable them while
leaving in debugfs support.

Subject: ath9k: remove rssi/antenna information from recv debug stats

The way this is implemented (simply storing the last value) is absolutely
worthless for debugging anything, and the same information is also available
through the MAC sample feature, so there's no point in keeping this around.

Subject: ath9k: fix signal strength reporting issues

On A-MPDU frames, the hardware only reports valid signal strength data for
the last subframe. The driver also mangled rx_stats->rs_rssi using the
ATH_EP_RND macro in a way that may make sense for ANI, but definitely
not for reporting to mac80211.
This patch changes the code to calculate the signal strength from the rssi
directly instead of taking the average value, and flag everything but
the last subframe in an A-MPDU to tell mac80211 to ignore the signal strength
entirely, fixing signal strength fluctuation issues reported by various
users.

From e19918855dc4822a24787a6d0048205b011e5ecb Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>

Subject: iwlwifi: move ucode loading to op_mode

uCode loading belongs to the op_mode, as it
is dependent on various things there and the
commands sent during it are specific to it.
Move the prototypes to iwl-agn.h to indicate
this. To make this possible, also move all
the calibration handling (which is op_mode
dependent after all).

From 0692fe41b36159be5d8c7d4eef0699e79c383c85 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:37 -0800
Subject: iwlwifi: split out firmware store

Through the driver, struct iwl_fw will
store the firmware. Split this out into
a separate file, iwl-fw.h, and make all
other code use it. To do this, also move
the log pointers into it, and remove the
knowledge of "nic" from everything.

Now the op_mode has a fw pointer, and
(unfortunately) for now the shared data
also needs to keep one for the transport
to access dump the error log -- I think
that will move later.

Since I wanted to constify the firmware
pointers, some more changes were needed.

From 965974a631756ab2729469b9ecadfe61ee44dfc5 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:38 -0800
Subject: iwlwifi: remove iwl-wifi.h

This file was recently introduced, but then
directly abused -- it contained private data
that shouldn't have been used by anything
but the implementation of firmware requests
and some very core code. Now that it is no
longer accessed by any code but the code in
iwl-drv.c, we can dissolve it.

Also rename the iwl_nic struct to iwl_drv to
better reflect where and how it is used.

From e10a0533a9172471b52bd9512838d766420a3baf Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:39 -0800
Subject: iwlwifi: add wrappers for command sending

Add wrappers to send commands from the DVM
op-mode (which essentially consists of the
current driver). This will allow us to move
specific sanity checks there.

Also, this removes iwl_trans_send_cmd_pdu()
since that can now be taken care of in the
DVM-specific wrapper.

From 721c32f72d8007dc0148ee88c046a4ade794a7b7 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:40 -0800
Subject: iwlwifi: move RF/CT kill check to command wrapper

Currently, we cannot send any commands when the
uCode is in RF or CT kill, but that will not be
true for all new uCode versions, so we need to
move the check into the uCode specific code.

Also remove the duplicate rfkill check.

Subject: iwlwifi: move lockdep assertion into DVM

The fact that the mutex must be held is an
implementation detail of DVM, but something
has to ensure that no two synchronous cmds
are submitted concurrently. Move the lockdep
assertion into the DVM-specific code, but
also make the transport abort if there are
two concurrently commands.

The assertion is much more useful though as
the transport check can only catch it when
it actually happens, while the assertion
makes sure it can't possibly happen.

Subject: iwlwifi: move rfkill status handling out of transport

The transport layer should only check the
hardware RF kill status, not impose any
policy or reaction based on it, so move
that out of it into the op_mode.

For now keep the restriction on loading
firmware, that will have to be removed
later.

Subject: iwlwifi: remove AMT check from transport

As iwl_prepare_card_hw() is idempotent (and
many cards support AMT anyway) there's no
point in calling iwl_prepare_card_hw() only
for AMT capable devices -- call it always
and simplify the code that way.

Subject: iwlwifi: remove shadow_reg_enable from hw_params

There's no need to copy shadow_reg_enable into
hw_params since it is a pure hardware parameter
that will never change, we can access it from
the config directly.

From 6c1011e1918be17f7f8ccca5442cd517f9c29d17 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>

Subject: iwlwifi: make tracing use device as identifier

Tracing used the priv pointer as an identifier,
which has the problem that we don't have it in
all code, and also some people say no pointers
should be "leaked" to userspace.

Use the device name instead, it is more useful
anyway.

Subject: iwlwifi: virtualize command queue full behaviour

When the command queue is full, the transport
will return -ENOSPC, but the reaction to that
depends on the op_mode. Virtualize that, the
DVM op_mode checks for CT-kill and restarts
the hardware otherwise.

We may be able to get rid of this callback by
putting the behaviour check into the wrapper
but that needs more careful evaluation.

Subject: iwlwifi: fix notification wait bug

In "iwlwifi: consolidate the start_device flow"
Emmanuel added the return if the fw isn't there
but forgot to take into account that the struct
for notification wait needs to be added only
after the check -- fix that.

From 4bd14dd5f77bbe3c51f50f4e86d3b8960e6a518c Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:58 -0800
Subject: iwlwifi: abstract out notification wait support

This will be sharable, but needs to live in the
op_mode as it is dependent on command processing.
Make a library out of the notification wait code.

Since I wrote all of the code originally and only
Intel employees changed it, we can also relicense
it to dual BSD/GPL.

Subject: iwlwifi: move ucode_owner to priv

The transport doesn't really need to know as
we can enforce it in the command wrapper.
Move the ucode_owner variable into priv and
do all enforcing there.

Subject: iwlwifi: move irq to PCIe

Even if the variable might also be used by other
transports, there's no need for anything outside
of the transport itself to access it, so move it
into the private area.

Subject: iwlwifi: move packet to transport

The base packet structure will (hopefully) be
the same for all transports, but what is in it
differs. Remove the union of all the possible
contents and move the packet itself into the
transport header file. This requires changing
all users of the union to just use pkt->data.

if we move it up a little in the file it can
be made static.

Subject: wl12xx: implement SW Tx watchdog

Track freed FW blocks during Tx. If no blocks were freed during a
predefined timeout, initiate a HW recovery. This helps in situations
when the FW watchdog fails.

Don't trigger recovery during activities that can temporarily stop
Tx. This includes:
- scanning
- buffering packets for sleeping stations (AP role)
- ROC on any role

the hw pointer anyway. Remove it.

Subject: iwlwifi: redesign PASSIVE_NO_RX workaround

The PASSIVE_NO_RX workaround currently crosses
through the op_mode and transport layers, which
is a bit odd. This also isn't necessary, if the
transport simply reports when queues are full
(or no longer full) the op_mode can keep track
of this state, and report to mac80211 only what
*it* thinks is appropriate. What is appropriate
can then be based on whether queues should be
stopped to wait for RX or not.

This significantly simplifies the transport API,
it no longer needs to expose anything to stop a
queue, nor to wake "any" queue, this can all be
handled in the upper layer completely.

Also simplify the handling to not be dependent
on the context, that makes little sense as the
queues are shared and both contexts have to be
on the same channel anyway.

Subject: iwlwifi: remove BT handlers from lib_ops

There's no need to have operations for
these as they simply depend on whether
the device has built-in bluetooth, so
just duplicate the information already
there (whether bt_params is present or
not).

The sensitivity parameters are never modified, so they
should be const. Also remove the unused max_nrg_cck
value to save some space.

In "iwlwifi: consolidate the start_device flow"
the code flow changed and the firmware is now
loaded by the transport layer, but the change
unfortunately lost error checking -- restore.

Subject: iwlwifi: dump stack when fail to gain access to the device

Print dump stack when the device is not responding. This should give
some more clue about the reason of failure. Also change the message we
print, since "MAC in deep sleep" is kinda confusing.

On the way add unlikely(), as fail to gain NIC access is hmm ...
unlikely.

Subject: iwlwifi: always check if got h/w access before write

Before we write to the device registers always check if
iwl_grap_nic_access() was successful.

On the way change return type of grab_nic_access() to bool, and add
likely()/unlikely() statement.

Subject: iwlwifi: cleanup/fix memory barriers

wmb(), rmb() are not needed when writel(), readl() are used as
accessors for MMIO. We use them indirectly via iowrite32(),
ioread32().

What is needed mmiowb(), for synchronizing writes coming from
different CPUs on PCIe bridge (see in patch comments). This
fortunately is not needed on x86, where mmiowb() is just
defined as compiler barrier. As iwlwifi devices are most likely
not used on anything other than x86, this is not so important
fix.

If device is disabled by rfkill switch, do not enable all interrupts,
but only CSR_INT_BIT_RF_KILL to receive rfkill state change. Unblocking
other interrupts might cause problems, since driver can not be prepared
for receive them.

Added a testmode command which tells iwl_rx_dispatch
to send the RX both as a notification to nl80211 and
with the registered RX handlers.

This is used for monitoring RX from userspace while preserving
the regular flows in the driver.

Subject: iwlwifi: remove messages from queue wake/stop

The only reason we ever stop/wake queues at
the transport level is now that they become
full (or non-full), so the messages aren't
useful any more -- remove them.

Subject: iwlwifi: don't delete AP station directly

With the mac80211 deauth sequence changes, the
station is deleted before the device is set
unassociated. This can cause the device to get
confused as it expects the station to be there
while the associated bit is set.

To fix this, do not delete the AP station from
the device when mac80211 asks for deletion,
instead just mark it as unused and rely on the
unassociated RXON to drop it from the station
database in the device.

Subject: mwifiex: correction in number of bitrates

In recent commit "mwifiex: correct bitrates advertised..", we have
removed 22Mbps and 72Mbps bitrates from supported bitrate array.
It means number of bitrates has reduced from 14 to 12.

Initialize ".n_bitrates" to array size instead of hardcoding it.

Subject: iwlwifi: move command queue number out of the iwl_shared struct

The command queue number is required by the transport
layer, but it can be determined only by the op mode.
Move this parameter to the dvm op mode, and configure
the transport layer using an API.

Subject: iwlwifi: restore PAN support

in iwlwifi: move setting up fw parameters

Meenakshi moved code up to configure the transport layer, but this
code read the sku before it was set (from the EEPROM). This killed
P2P.
Only the ucode_flags are needed to configure the transport layer, not
the sku which _must_ be set after the EEPROM is read.

We need to reconfigure the transport in case the EEPROM disabled PAN
support. This is not the nicest thing to do, but we have no choice.
Document that we are allowed to configure the transport several times
before start_fw, but not after.

- *
- * This module implements the virtual ethernet device for iSeries LPAR
- * Linux.  It uses hypervisor message passing to implement an
- * ethernet-like network device communicating between partitions on
- * the iSeries.
- *
- * The iSeries LPAR hypervisor currently allows for up to 16 different
- * virtual ethernets.  These are all dynamically configurable on
- * OS/400 partitions, but dynamic configuration is not supported under
- * Linux yet.  An ethXX network device will be created for each
- * virtual ethernet this partition is connected to.
- *
- * - This driver is responsible for routing packets to and from other
- *   partitions.  The MAC addresses used by the virtual ethernets
- *   contains meaning and must not be modified.
- *
- * - Having 2 virtual ethernets to the same remote partition DOES NOT
- *   double the available bandwidth.  The 2 devices will share the
- *   available hypervisor bandwidth.
- *
- * - If you send a packet to your own mac address, it will just be
- *   dropped, you won't get it on the receive side.
- *
- * - Multicast is implemented by sending the frame frame to every
- *   other partition.  It is the responsibility of the receiving
- *   partition to filter the addresses desired.
- *
- * Tunable parameters:
- *
- * VETH_NUMBUFFERS: This compile time option defaults to 120.  It
- * controls how much memory Linux will allocate per remote partition
- * it is communicating with.  It can be thought of as the maximum
- * number of packets outstanding to a remote partition at a time.

 arguments to request_irq and free_irq are compatible

Convert calls to free_irq so that the second argument is the same as the
last argument of the corresponding call to request_irq.  Without this
property, free_irq does nothing.

Subject: net/wireless: ipw2x00: remove unused definitions for regulatory
 domain

ipw2200 driver does not use these defines, it uses geo struct instead.
Therefore remove them from its header.

Note: we keep them in the ipw2100 driver's header, because the driver
still uses them.

Subject: rt2x00: Fix beacon skew in rt2800pci

rt2800pci is suffering from beacon skew in AP mode. Some powersaving
clients (like VOIP phones) are getting into trouble after some time
when the beacon skew is getting too big.

The ralink legacy drivers contain a function that indicates that the
beacon timer is off by 1us per tbtt. And this function works around
that by reducing the beacon interval for every 64th beacon transmission
by 64us (the smallest possible value). Do the same in rt2800pci.

This allows proper powersaving when rt2800pci is used in AP mode.

Subject: iwlwifi: abstract out missing SEQ_RX_FRAME workaround

Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround
warning with a statistics notification, this means we
can't just remove it as we'd hoped.

Abstract it out so that the higher layer can configure
this as a kind of "filter" in the transport.

it doesn't indicate why or where it came from,
so make it a warning in order to identify it.

Subject: iwlwifi: move wait_command_queue from shared to trans

This wait queue really belongs to the transport
layer, as it is used for sending synchronous
commands to the HW.

However, only op_mode knows about errors and
exceptional conditions, so make this queue
accessible by the op_mode.

Subject: iwlwifi: explicitly track whether INIT uCode was run

Remove IWL_UCODE_NONE from enum iwl_ucode_type which,
by being the default value in 0-initialized memory,
implicitly allowed us to track whether any uCode had
ever been loaded successfully (which would have been
the INIT uCode) and instead explicitly track whether
or not INIT uCode has been run.

Subject: iwlwifi: more modularity in fw images and sections

Changed iwl_firmware_pieces structure to support an array of
separate images, and an array of sections for each image.

In fw_sec and fw_desc structures, added a field for
offset from the HW address, to support 16.0 uCode that
provides an offset instead of any other data about the section.
This field is filled with default values when parsing instruction
or data section.

Subject: iwlwifi: change struct iwl_fw

Change iwl_fw struct to hold an array of fw_img instead of
three separated instances.

Change fw_img to hold an array of fw_desc instead of two
separate descriptors for instructions and data.

Change load_given_ucode, load_section, verification functions
etc. to support this structure.

From ef31bef6216db76950c38f1993b45953402f4c63 Mon Sep 17 00:00:00 2001

Subject: net/hyperv: Fix data corruption in rndis_filter_receive()

Limiting the memcpy to be the sizeof(struct rndis_message) can truncate
the message if there are Per-Packet-Info or Out-of-Band data.

In my earlier patch (commit 45326342), the unnecessary kmap_atomic and
kunmap_atomic surrounding this memcpy have been removed because the memory
in the receive buffer is always mapped. This memcpy is not necessary
either. To fix the bug, I removed the memcpy.

Subject: bnx2x: ethtool now returns unknown speed/duplex

Previously, unless both interface and link were up, ethtool returned
the requested speed/duplex when asked for the interface's settings.
This change will now enable the driver to answer correctly (i.e.,
return unknown as its answer).

A bug was introduced with the following patch:

  Author: Eric Dumazet <eric.dumazet@gmail.com>
  igb: Add support for byte queue limits.

The ethtool offline tests will cause a perpetual link flap, this
is because the tests also need to account for byte queue limits (BQL).

Subject: ixgbe: remove tie between NAPI work limits and interrupt moderation

As noted by Ben Hutchings and David Miller, work limits for NAPI
should not be tied to interrupt moderation parameters.  This
should be handled by NAPI, possibly through sysfs.

Neil Horman & Stephen Hemminger are working on a solution for
NAPI currently.  In the meantime, remove this tie between
work limits and interrupt moderation.

Subject: net: Fix issue with netdev_tx_reset_queue not resetting queue from
 XOFF state

We are seeing dev_watchdog hangs on several drivers.  I suspect this is due
to the __QUEUE_STATE_STACK_XOFF bit being set prior to a reset for link
change, and then not being cleared by netdev_tx_reset_queue.  This change
corrects that.

In addition we were seeing dev_watchdog hangs on igb after running the
ethtool tests.  We found this to be due to the fact that the ethtool test
runs the same logic as ndo_start_xmit, but we were never clearing the XOFF
flag since the loopback test in ethtool does not do byte queue accounting.

Subject: ixgbe: Do no clear Tx status bits since eop_desc provides enough info

There isn't any need to clear the status bits in the descriptors due to the
fact that the eop_desc provides enough information for us to know
that we have cleaned to the last packet that the software has put on the
ring.  The status bits are cleared as a part of putting the frame on the
ring so as long as we do not read the descriptor bit prior to reading the
value eop_desc we should be able to guarantee that we will not clean beyond
the end of the current data stream.

Subject: ixgbe: Address issues with Tx WHTRESH value not being set correctly

This change is meant to address the fact that the tx_itr_setting was
dropping to 0 when no separate Tx vectors were provided.  This had resulted
in the driver incorrectly configuring the Tx ring with a WTHRESH of 1 in
order to avoid Tx hangs even though that was not necessary. This change
makes it so that we instead take a look at the Tx ring's q_vector to
determine if the ring will have an ITR value less than 8us.

This change corrects an issue in which Adaptive Interrupt Moderation was
not changing values due to the fact that we were performing an and
operation on the resultant value that was causing the value to never change
from the default 20K interrupts per second.

Subject: ixgbe: Default to queue pairs when number of queues is less than CPUs

The old code had several errors in how it was determining the vector
budget.  In order to simplify things this patch updates the code so that it
will attempt to always allocated paired Rx/Tx vectors instead of attempting
to allocate individual vectors when the number of queues is less than the
number of CPUs.

Subject: ixgbe: Allocate rings as part of the q_vector

This patch makes the rings a part of the q_vector directly instead of
indirectly.  Specifically on x86 systems this helps to avoid any cache
set conflicts between the q_vector, the tx_rings, and the rx_rings as the
critical stride is 4K and in order to cross that boundary you would need to
have over 15 rings on a single q_vector.

In addition this allows for smarter allocations when Flow Director is
enabled.  Previously Flow Director would set the irq_affinity hints based
on the CPU and was still using a node interleaving approach which on some
systems would end up with the two values mismatched.  With the new approach
we can set the affinity for the irq_vector and use the CPU for that
affinity to determine the node value for the node and the rings.

Subject: ixgbe: Add iterator for cycling through rings on a q_vector

Since there are multiple spots where we have to cycle through all of the
rings on a q_vector it makes sense to just add a function for iterating
through all of them.

Subject: ixgbe: Simplify logic for ethtool loopback frame creation and testing

This change makes it a bit easier to do the loopback frame creating and
testing.  Previously we were doing an and to drop the last bit, and then
dividing the frame_size by 2 in order to get locations for frame bytes and
testing.  Instead we can simplify it by just shifting the register one bit
to the right and using that for the frame offsets.

This change also replaces all instances of rx_buffer_info with just
rx_buffer since that is closer to the name of the actual structure being
used and can save a few extra characters.

In addition I have updated the logic for cleaning up a test frame so that
we pass an rx_buffer instead of the sk_buff.  The main motivation behind
this is changes that will replace the sk_buff with just a page in the
future.

Subject: ath6kl: fix regression in ath6kl_upload_board_file()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

My patch 24fc32b3 ("ath6kl: add ath6kl_bmi_write_hi32()") caused a regression
in ath6kl_upload_board_file() and the board_address variable was not
properly initialised in some cases:

ath6kl/init.c:1068:6: warning: ‘board_address’ may be used uninitialized
in this function

Most likely this broke ar6004 support but I can't test that right now.

Subject: b43legacy: Load firmware from work queue instead of from probe
 routine

Recent changes in udev are causing problems for drivers that load firmware
from the probe routine. As b43legacy has such a structure, it must be changed.
As this driver loads 3 or 4 firmware files, changing to the asynchronous routine
request_firmware_nowait() would be complicated. In this implementation, the probe
routine starts a work queue that calls the firmware loading routines.

Subject: b43: Load firmware from a work queue and not from the probe routine

Recent changes in udev are causing problems for drivers that load firmware
from the probe routine. As b43 has such a structure, it must be changed.
As this driver loads more than 1 firmware file, changing to the asynchronous routine
request_firmware_nowait() would be complicated. In this implementation, the probe
routine starts a queue that calls the firmware loading routines.

Subject: mwifiex: use usleep_range instead of udelay

For the delay of 10 uSec or more usleep_range is prefered.
Unlike udelay, sleep_range avoids large number of undesired

Subject: mac80211: rename bss_conf timestamp to last_tsf

This value is not really very useful by itself,
yet some drivers (including iwlwifi until I can
figure out what it should do) use it. At least
rename it to "last_tsf" to indicate the meaning
and add a note that it may be really old.

I suspect the value may become useful combined
with the rx_status->mactime, but we don't (yet)
store that value and pass it to the driver.

Subject: ixgbe: Do not disable read relaxed ordering when DCA is enabled

A previous fix had gone though and disabled relaxed ordering for Rx
descriptor read fetching.  This was not necessary as this functions
correctly and has no ill effects on the system.

In addition several of the defines used for the DCA control registers were
incorrect in that they indicated descriptor effects when they actually had
an impact on either data or header write back.  As such I have update these
to correctly reflect either DATA or HEAD.

Subject: ixgbe: Replace eitr_low and eitr_high with static values in
 ixgbe_update_itr

There isn't much point in using variables to store the values of eitr_low
and eitr_high since they are not user changeable.  As such I am replacing
them with the constants 10 and 20 in order to avoid any confusion on what
the values actually are.

Subject: ixgbe: Fix race condition where RX buffer could become corrupted.

There was a race condition in the reset path where the RX buffer
could become corrupted during Fdir configuration.This is due to
a HW bug.The fix right now is to lock the buffer while we do the
fdir configuration.Since we were using similar workaround for another bug,
I moved the existing code to a function and reused it.HW team also recommended
that IXGBE_MAX_SECRX_POLL value be changed from 30 to 40.The erratum for this
bug will be published in the next release 82599 Spec Update

Subject: ixgbe: dcb: use DCB config values for FCoE traffic class on open

Disabling and enabling DCB can cause FCoE hardware initialization to
occur on the incorrect traffic class when the up2tc mapping has not
yet been reconfigured.

Fix this by using the DCB configuration maps that are correct
and will be pushed at mqprio after DCB driver setup completes
successfully.

Subject: rt2x00: Set IEEE80211_HW_REPORTS_TX_ACK_STATUS in rt2800

rt2800 already reports the tx ack status of each frame back to mac80211.
Advertise this by setting IEEE80211_HW_REPORTS_TX_ACK_STATUS for rt2800.
This allows some mac80211 features like frame loss notifications to work
with rt2800.

Use a small helper function to decide whether FCC is to be
used.

Subject: ath9k: Remove aggregation flags

SC_OP_TXAGGR and SC_OP_RXAGGR are not really needed.
The HT capabilities of the station and HW can be used instead.

Subject: ath9k: Fix multi-VIF BSS handling

mac80211 provides short preamble information and ERP protection
information on a per-BSS basis, which can be used. Remove flags
stored in the driver, which was incorrect since they were being used
in a global manner.

Subject: rt2x00: rt2800usb: rework txdone code

Patch change txdone code to make it similar like txdone in rt2800pci,
process only one entry from queue matching tx status.

Before we processed all pending entries from queue until PACKEDID match,
that caused that we do not report tx statuses correctly.

Subject: rt2x00: rt2800usb: rework txstatus code

Currently we read tx status register after each urb data transfer. As
callback procedure also trigger reading, that causing we have many
"threads" of reading status. To prevent that introduce TX_STATUS_READING
flags, and check if we are already in process of sequential reading
TX_STA_FIFO, before requesting new reads.

Change timer to hrtimer, that make TX_STA_FIFO overruns less possible.
Use 200 us for initial timeout, and then reschedule in 100 us period,
this values probably have to be tuned.

Make changes on txdone work. Schedule it from
rt2800usb_tx_sta_fifo_read_completed() callback when first valid status
show up. Check in callback if tx status timeout happens, and schedule
work on that condition too. That make possible to remove tx status
timeout from generic watchdog. I moved that to rt2800usb.

Loop in txdone work, that should prevent situation when we queue work,
which is already processed, and after finish work is not rescheduled
again.

Subject: rt2x00: rt2800usb: do not check packedid for aggregated frames

Tx statuses of aggregated subframes contain packetid of first subframe
in the AMPDU. We can not identify AMPDU subframes based on packedid, so
simply assume that status match first pending frame in the queue. Thats
mostly the same what 2800pci do.

Subject: rt2x00: rt2800usb: limit tx queues length

TX status fifo is limited to 16 elements. When we send more frames than
that, we can easily loose status, what is not good for rate scaling
algorithm.

On my testing the change does not degrade performance, actually make
is slightly better. Additionally with the patch I can see much less
various rt2x00 warnings in dmesg.

TXQ_FLAG_TXOKINT_ENABLE and TXQ_FLAG_TXERRINT_ENABLE are always set and

Simplify the code that tests for these flags.

The ATH9K_HW_CAP_AUTOSLEEP check is bogus, the rx status area needs to be
cleared on all non-EDMA PCI/AHB based chipsets anyway.
Limit the memset to the rx status area to improve performance.

Subject: libertas: remove dump_survey implementation

libertas provides a dump_survey implementation based on reading of
a RSSI value. However, this RSSI value is calculated based on the
last received beacon from the associated AP - it is not a good
way of surveying a channel in general, and even causes an error
if the card is not associated to a network.

As this is not appropriate as a survey, remove it. This fixes an
issue where something in userspace is repeatedly calling site-survey
during boot, resulting in many repeated errors as the RSSI value cannot
be read before associating.

Subject: gianfar: Add support for byte queue limits.

Add support for byte queue limits (BQL), based on the similar
modifications made to intel/igb/igb_main.c from Eric Dumazet
in commit bdbc063129e811264cd6c311d8c2d9b95de01231
	"igb: Add support for byte queue limits."

A local variable for tx_queue->qindex was introduced in
gfar_clean_tx_ring, since it is now used often enough to warrant it,
and it cleans up the readability somewhat as well.

Subject: asix: asix_rx_fixup surgery to reduce skb truesizes

asix_rx_fixup() is complex, and does some unnecessary memory copies (at
least on x86 where NET_IP_ALIGN is 0)

Also, it tends to provide skbs with a big truesize (4096+256 with
MTU=1500) to upper stack, so incoming trafic consume a lot of memory and
I noticed early packet drops because we hit socket rcvbuf too fast.

Switch to a different strategy, using copybreak so that we provide nice
skbs to upper stack (including the NET_SKB_PAD to avoid future head
reallocations in some paths)

With this patch, I no longer see packets drops or tcp collapses on
various tcp workload with a AX88772 adapter.

Subject: netxen: qlogic ethernet : Fix endian bug.

Change the datatype of "ip_addr" to __be32 as 'ip' should be in
big endian format.

Adapter needs "ip address" in big endian format stored at lower 32bit
of req.word[1]. netxen_config_ipaddr() now receives 'ip' in big endian
format. To satisfy adapter's need, use memcpy() to copy byte by byte
of 'ip' into lower 32bit of req.word[1].

Mac address and serial number of adapter need to be in little endian format.
Change the data type of the related  variables to __le32 / __le64 or cast it
explicitly to __le32 / __le64 depending upon the requirement.

Subject: stmmac: Add device-tree support

This patch adds support to configure the STMMAC ethernet driver via
device-tree instead of platform_data.

Currently, only the properties needed on SPEAr600 are provided. All
other properties should be added once needed on other platforms.

Subject: usbnet: use netif_tx_wake_queue instead of netif_start_queue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If host is going to autosuspend function with two interfaces and
if IP packet has arrived in-between of two usbnet_suspend() callbacks,
i.e usbnet_resume() is called in-between, tx data flow is stopped.
When autosuspend timer expires and device is put to autosuspend
again, tx queue is waked up and data can be sent again.
This behavior might be repeated several times in a row.

Tested on Intel/ARM.

Subject: ixgbe: Support RX-ALL feature flag.

This allows the NIC to receive all frames available, including
those with bad FCS, ethernet control frames, and more.

Tested by sending frames with bad FCS.

From f800326dca7bc158f4c886aa92f222de37993c80 Mon Sep 17 00:00:00 2001
From: Alexander Duyck <alexander.h.duyck@intel.com>

Subject: ixgbe: Replace standard receive path with a page based receive

This patch replaces the existing Rx hot-path in the ixgbe driver with a new
implementation that is based on performing a double buffered receive.  The
ixgbe driver already had something similar in place for its' packet split
path, however in that case we were still receiving the header for the
packet into the sk_buff.  The big change here is the entire receive path
will receive into pages only, and then pull the header out of the page and
copy it into the sk_buff data.  There are several motivations behind this
approach.

First, this allows us to avoid several cache misses as we were taking a
set of cache misses for allocating the sk_buff and then another set for
receiving data into the sk_buff.  We are able to avoid these misses on
receive now as we allocate the sk_buff when data is available.

Second we are able to see a considerable performance gain when an IOMMU is
enabled because we are no longer unmapping every buffer on receive.
Instead we can delay the unmap until we are unable to use the page, and
instead we can simply call sync_single_range on the half of the page that
contains new data.

Finally we are able to drop a considerable amount of code from the driver
as we no longer have to support 2 different receive modes, packet split and
one buffer.  This allows us to optimize the Rx path further since less
branching is required.

are making it unnecessarily complex due to a workaround required for 82599
when SR-IOV is enabled.

Subject: ixgbe: Modify setup of descriptor flags to avoid conditional jumps

This change makes it more likely that the descriptor flags setup will use
cmov instructions instead of conditional jumps when setting up the flags.
The advantage to this is that the code should just flow a bit more
smoothly.

To do this it is necessary to set the TX_FLAGS_CSUM bit in tx_flags when
doing TSO so that we also do the checksum in addition to the segmentation
offload.

Subject: ixgbe: Use packets to track Tx completions instead of a seperate
 value

A separate value was added to track Tx completions in order to determine if
the Tx unit was hung.  However we can do the same thing using the number of
packets completed without having to add another stat to the Tx ring.

Subject: ixgbe: Place skb on first buffer_info structure to avoid using stack
 space

Instead of keeping a local copy of the skb on the stack for as long as long
as we do it makes sense to instead just place it on the first tx_buffer
structure so that we can save space on the stack and avoid unnecessary
read/write operations copying the pointer out of the stack and onto the
ring later.

Subject: ixgbe: Write gso_segs and bytcount to the ring sooner

This change makes it so that gso_segs and bytecount are written to the ring
sooner.  This helps to simplify the logic for the two since segmentation
offloads can now update them within their own function.

From 729739b754affa482e92fa7836e4066096089d11 Mon Sep 17 00:00:00 2001
From: Alexander Duyck <alexander.h.duyck@intel.com>
Date: Wed, 8 Feb 2012 07:51:06 +0000
Subject: ixgbe: always write DMA for single_mapped value with skb

This change makes it so that we always write the DMA address for the skb
itself on the same tx_buffer struct that the skb is written on.  This way
we don't need the MAPPED_AS_PAGE flag and we always know it will be the
first DMA value that we will have to unmap.

In addition I have found an issue in which we were leaking a DMA mapping if
the value happened to be 0 which is possible on some platforms.  In order
to resolve that I have updated the transmit path to use the length instead
of the DMA mapping in order to determine if a mapping is actually present.

One other tweak in this patch is that it only writes the olinfo information
on the first descriptor.  As it turns out it isn't necessary to write it
for anything but the first descriptor so there is no need to carry it
forward.

Subject: gianfar: use netif_tx_queue_stopped instead of
 __netif_subqueue_stopped

The __netif_subqueue_stopped() just does the following:

        struct netdev_queue *txq = netdev_get_tx_queue(dev, queue_index);
        return netif_tx_queue_stopped(txq);

and since we already have the txq in scope, we can just call that
directly in this case.

Subject: ixgbe: Store Tx flags and protocol information to tx_buffer sooner

This change makes it so that we store the tx_flags and protocol information
to the tx_buffer_info structure sooner. This allows us to avoid unnecessary
read/write transactions since we are placing the data in the final location
earlier.

Subject: ixgbe: Update layout of ixgbe_ring structure to improve cache
 performance

This change makes it so that only the 2nd cache line in the ring structure
should see frequent updates.  The advantage to this is that it should
reduce the amount of cross CPU cache bouncing since only the 2nd cache line
will be changing between most network transactions.

Subject: ixgbe: Move poll routine in order to improve readability

This change relocates the ixgbe_poll routine so it is right next to the
interrupt routine that schedules and calls it.

Subject: ixgbe: drop err_eeprom tag which is at same location as err_sw_init

The err_eeprom and err_sw_init tags both go to the same location.  So
instead of maintaining two tags this patch combines them so we only use
err_sw_init.

Subject: ixgbe: Two minor fixes for RSS and FDIR set queues functions

This change fixes two minor issues. The first was the fact that we were
setting the return value to false twice in the set_rss_queues function.
The second is the fact that we should have been using "min_t(int," instead
of "min((int)" in set_fdir_queues.

From 567d2de291b5ddb83654c5e87c14b4c6fa7216ed Mon Sep 17 00:00:00 2001
From: Alexander Duyck <alexander.h.duyck@intel.com>

Subject: ixgbe: Correct flag values set by ixgbe_fix_features

This patch replaces the variable name data with the variable name features
for ixgbe_fix_features and ixgbe_set_features.  This helps to make some
issues more obvious such as the fact that we were disabling Rx VLAN tag
stripping when we should have been forcing it to be enabled when DCB is
enabled.

In addition there was deprecated code present that was disabling the LRO
flag if we had the itr value set too low.  I have updated this logic so
that we will now allow the LRO flag to be set, but will not enable RSC
until the rx-usecs value is high enough to allow enough time for Rx packet
coalescing.

Subject: bnx2x: revised driver prints

We've revised driver prints, changing the mask of existing prints
to allow better control over the debug messages, added prints to
error scenarios, removed unnecessary prints and corrected some spelling.
Please note that this patch contains lines with over 80 characters,
as string messages were kept in a single line.

Subject: bnx2x: changed iscsi/fcoe mac init and macros

This includes changes in macros to better distinguish between the two
protocols, and slightly changed the way their macs are set.
Notice this file contains string print lines with more than 80 characters,
as to not break prints.

Subject: bnx2x: consistent statistics for old FW

Previously applied patch making the bnx2x statistics consistent
did not apply to old FWs. This remedies it, extending the consistent
behaviour to all drivers.

Subject: ixgbe: fix namespace issues when FCoE/DCB is not enabled

Resolve namespace issues when FCoE or DCB is not enabled.
The issue is with certain configurations we end up with namespace
problems. A simple example:

ixgbe_main.c
 - defines func A()
 - uses func A()

ixgbe_fcoe.c
 - uses func A()

ixgbe.h
 - has prototype for func A()

For default (FCoE included) all is good.  But when it isn't the namespace
checker complains about how func A() could be static.

To resolve this, created a ixgbe_lib file to contain functions used
by DCB/FCoE and their helper functions so that they are always in
namespace whether or not DCB/FCoE is enabled.

Subject: net/hyperv: Fix the code handling tx busy

Instead of dropping the packet, we keep the skb buffer, and return
NETDEV_TX_BUSY to let upper layer retry send. This will not cause
endless loop, because the host is taking data away from ring buffer,
and we have called the stop_queue before returning NETDEV_TX_BUSY.

The stop_queue was called in the function netvsc_send() in file
netvsc.c, then it returns to rndis_filter_send(), which returns to
netvsc_start_xmit() in file netvsc_drv.c. So the NETDEV_TX_BUSY is
indeed returned AFTER queue is stopped.

Subject: ixgbe: Fix issues with SR-IOV loopback when flow control is disabled

This patch allows us to avoid a Tx hang when SR-IOV is enabled.  This hang
can be triggered by sending small packets at a rate that was triggering Rx
missed errors from the adapter while the internal Tx switch and at least
one VF are enabled.

This was all due to the fact that under heavy stress the Rx FIFO never
drained below the flow control high water mark.  This resulted in the Tx
FIFO being head of line blocked due to the fact that it relies on the flow
control high water mark to determine when it is acceptable for the Tx to
place a packet in the Rx FIFO.

The resolution for this is to set the FCRTH value to the RXPBSIZE - 32 so
that even if the ring is almost completely full we can still place Tx
packets on the Rx ring and drop incoming Rx traffic if we do not have
sufficient space available in the Rx FIFO.

Subject: bonding: send igmp report for its master

Liang Zheng(lzheng@redhat.com) found that in the following topo,
bonding does not send igmp report when we trigger a fail-over of bonding.

eth0--
      |-- bond0 -- br0
eth1--

modprobe bonding mode=1 miimon=100 resend_igmp=10
ifconfig bond0 up
ifenslave bond0 eth0 eth1

brctl addbr br0
ifconfig br0 192.168.100.2/24 up
brctl addif br0 bond0

Add 192.168.100.2(br0) into a multicast group, like 224.10.10.10,
then trigger a fali-over in bonding.
You can see that parameter "resend_igmp" does not work.

The reason is that when we add br0 into a multicast group,
it does not propagate multicast knowledge down to its ports.

If we choose to propagate multicast knowledge down to all ports for bridge,
then we have to track every change that is done to bridge, and keep a backup
for all ports. It is hard to track, I think.

Instead I choose to modify bonding to send igmp report for its master.

Changelog:
V2: correct comments
V3: move this check into bond_resend_igmp_join_requests()
V4: only send igmp reports if bond is enslaved to a bridge

Subject: mlx4_core: fix race on comm channel

Prevent race condition between commands on comm channel.
Happened while unloading the driver when switching from
event to polling mode. VF got completion on the last command
before switching to polling mode, but toggle was not changed.
After the fix - VF will not write the next command before
toggle is updated.

Subject: netdev: driver: ethernet: Add TI CPSW driver

This patch adds support for TI's CPSW driver.

The three port switch gigabit ethernet subsystem provides ethernet packet
communication and can be configured as an ethernet switch. Supports
10/100/1000 Mbps.
