IE's are parsed from beacon buffer and stored locally using
mwifiex_update_bss_desc_with_ie() function.
Sometimes the local pointers point to the data inside IE, but
while using them it is assumed that they are pointing to the IE
itself.
These issues are fixed in this patch.

This option allows driver to finish pending operations in
disconnect handler by not killing URBs after usb_deregister
call.
We will get rid of global pointer 'usb_card' by moving code
from cleanup_module() to disconnect(). This will help to match
with our handling for SDIO and PCIe interfaces.

For PCIe, aggregate more AMSDU packets till PCIe TXBD is full.
For SDIO, aggregation was disabled for AMSDU packets because
AMSDU aggregated packet size is already 4K or 8K, SDIO Multiport
Aggregation feature didn't use to gain much previously.
Now with increased multiport aggregation buffer, we can enable
it for AMSDU packets.

Currently Tx and Rx buffer sizes are 8K and 16K respectively for
all chipsets. We will change them to 32K for SD8897 and 16K for
older chipsets. SD8897 chipset has more SDIO data ports than
older chipsets.
This patch will help to improve throughput numbers.

Sometimes, due to the race between Rx path and WMI_BA_STATUS_EVENTID WMI event,
few frames may be passed to the stack before reorder buffer allocated.
Then, after BACK establishment, it start getting frames with sequence number ahead of
SSN, and it get interpreted as missing frames. Then, BACK mechanism will wait
for missing frames; data traffic will be stopped. In case of interface configured
for DHCP, this data delay causes DHCP failure.
Relax checking for sequence number; use sequence of 1-st frame handled by the buffer
as SSN for this buffer.
This is work-around, real fix should be done when proper BACK mechanism implemented.

HW should never attempt to perform DMA for unused queues.
For rtl8187se this is ensured by setting a dedicated register at
init time, before enabling TX.
In rtl8180/5 the register is only written at the first TX (because
in rtl8180/5 it serves also to kick DMA for used queues).
This should be enough, but it's worth to add a register write at
init time, before enabling TX.

Currently this have no functional impact because the high-priority

The calculation for the length of the string is off because it assumes

at most 31 characters and NUL. I have removed the dial[] buffer because
it isn't needed.
The maximum length of the string is actually 79 characters and a NUL. I

====================
net: mdio-gpio enhancements
The following series of patches adds support for active-low gpio pins
as well as for systems with separate MDI and MDO pins to the mdio-gpio
driver.
A board using those features is based on a COM Express CPU board.
The COM Express standard supports GPIO pins on its connector,
with one caveat: The pins on the connector have fixed direction
and are hard configured either as input or output pins.
The COM Express Design Guide [1] provides additional details.
The hardware uses three of the GPO/GPI pins from the COM Express board
to drive an MDIO bus. Connectivity between GPI/GPO pins and the MDIO bus
is as follows.
GPI2 --------------------+------------ MDIO
|
+--------+ |
GPO2 ---+---G | |
| | | |
4.7k | 2N7002 D---+
| | |
+---S |
| +--------+
GND
GPO1 --------------------------------- MDC
To support this hardware, two extensions to the driver were necessary.
- Due to the FET in the MDO path (GPO2), the MDO signal is inverted.
The driver therefore has to support active-low GPIO pins.
- The MDIO signal must be separated into MDI and MDO.
Those changes are implemented in patch 2/3 and 3/3.
Patch 1/3 simplifies the error path and thus the subsequent
patches.

In my special case, when a packet is redirected from veth0 to lo,
its skb->dev->ifindex would be LOOPBACK_IFINDEX. Meanwhile we
pass the hard-coded LOOPBACK_IFINDEX to fib_validate_source()
in ip_route_input_slow(). This would cause the following check
in fib_validate_source() fail:
(dev->ifindex != oif || !IN_DEV_TX_REDIRECTS(idev))
when rp_filter is disabeld on loopback. As suggested by Julian,
the caller should pass 0 here so that we will not end up by
calling __fib_validate_source().

As suggested by Julian:
Simply, flowi4_iif must not contain 0, it does not
look logical to ignore all ip rules with specified iif.
because in fib_rule_match() we do:
if (rule->iifindex && (rule->iifindex != fl->flowi_iif))
goto out;
flowi4_iif should be LOOPBACK_IFINDEX by default.
We need to move LOOPBACK_IFINDEX to include/net/flow.h:
1) It is mostly used by flowi_iif
2) Fix the following compile error if we use it in flow.h

====================
net: mvneta: fix usage as a module, and support QSGMII properly
This set of patches is a new attempt at fixing the operation of the
mvneta driver when built as a module. For the record, the previous
attempt, merged in commit e3a8786c10e75903f1269474e21fe8cb49c3a670
('net: mvneta: fix usage as a module on RGMII configurations') caused
problems for all RGMII configurations.
In fact, it turned out that the MAC to PHY connection on the Armada XP
GP, which was described as using RGMII-ID according to its Device
Tree, is in fact a QSGMII connection. And the RGMII and QSGMII
configurations have to be handled in a different way in the driver,
because the SERDES configuration is different in those two cases.
So, this patch series fixes that by:
* Adding minimal handling of a "qsgmii" connection type in the PHY
layer. Mainly to make sure that a "qsgmii" phy-mode in the Device
Tree is recognized, and handed over to the driver as
PHY_INTERFACE_QSGMII.
* Changing the mvneta driver to properly configure the RGMIIEn and
PCSEn bits in the GMAC_CTRL_2 register, and configure the SERDES
register, in the three possible cases: RGMII, SGMII and QSGMII.
* Updating the Device Tree of the Armada XP GP board to reflect the
fact that it uses a QSGMII MAC/PHY connection.
PATCH 1 and 2 would be merged by David Miller, through the net tree,
while PATCH 3 would be merged by the mach-mvebu maintainers, through
their tree and arm-soc.
This set of patches has been tested on:
* Armada XP GP (four QSGMII interfaces)
* Armada XP DB (two RGMII interfaces and two SGMII interfaces)
* Armada 370 Mirabox (two RGMII interfaces)
I've tested both the driver built-in, and compiled as a module.
Since the last attempt at fixing this was quite a fiasco, I'd like
this new attempt to be tested more widely before being applied. I'll
try to do some testing on other Armada boards I have, but independent
testing from other persons would also be appreciated.
Note that these patches apply after reverting the previous attempt,
obviously.

Commit 5445eaf309ff ('mvneta: Try to fix mvneta when compiled as
module') fixed the mvneta driver to make it work properly when loaded
as a module in SGMII configuration, which was tested successful by the
author on the Armada XP OpenBlocks AX3, which uses SGMII.
However, some other platforms, namely the Armada XP GP don't use
SGMII, but a QSGMII connection between the MAC and the PHY, and this
case was not supported by the mvneta driver, which was relying on
configuration put in place by the bootloader. While this works when
the mvneta driver is built-in (because clocks are not gated), it
breaks when mvneta is built as a module, because the clock is gated
(all configuration is lost) and then re-enabled when the mvneta driver
is loaded.
In order to support all of RGMII, SGMII and QSGMII, this commit
reworks how the PHY interface configuration is done, and simplifies
it: it removes the mvneta_port_sgmii_config() and
mvneta_gmac_rgmii_set() functions, which were strange because
mvneta_gmac_rgmii_set() was called in all cases, even for SGMII
configurations. Also, the mvneta_gmac_rgmii_set() function was taking
a boolean as argument, which was always true.
Instead, all the PHY interface configuration logic is moved into the
mvneta_port_power_up() function, in a much simpler 'switch' construct,
with four cases:
- QSGMII: the RGMIIEn bit, the PCSEn bit in GMAC_CTRL_2 are set, and
the SERDES is configured in QSGMII. Technically speaking,
configuring the SERDES of the first port would be sufficient, but
it is simpler to do it on all ports.
- SGMII: the RGMIIEn bit, the PCSEn bit in GMAC_CTRL_2 are set, and
the SERDES is configured as SGMII.
- RGMII: the RGMIIEn bit in GMAC_CTRL_2 is set. The PCSEn bit is kept
cleared, and no SERDES configuration is done, because RGMII is not
using SERDES lanes.
- other: an error is returned. For this reason, the
mvneta_port_power_up() now returns an int instead of nothing, and
the return value is checked by mvneta_probe().
This has been successfully tested on:
* Armada XP DB, which has two RGMII and two SGMII connections
* Armada XP GP, which uses QSGMII for its four interfaces
* Armada 370 Mirabox, which has two RGMII connections

This commit adds the necessary definitions for the PHY layer to
recognize "qsgmii" as a valid PHY interface. A QSMII interface, as
defined at
http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface,
is "is a method of combining four SGMII lines into a 5Gbit/s
interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX
data and a single LVDS clock signal. QSGMII uses significantly fewer
signal lines than four SGMII busses."
This type of MAC <-> PHY connection might require special handling on
the MAC driver side, so it should be possible to express this type of
MAC <-> PHY connection, for example in the Device Tree.

When an MCDI command times out (whether or not we find it
completed when we poll), call efx_mcdi_abandon(), which tells
all subsequent MCDI calls to fail-fast, and queues up an FLR.
Because an FLR doesn't lead to receiving any reboot even from
the MC (unlike most other types of reset), we have to call
efx_ef10_reset_mc_allocations.
In efx_start_all(), if a reset (of any kind) is pending, we
bail out.
Without this, attempts to reconfigure (e.g. change mtu) can
cause driver/mc state inconsistency if the first MCDI call
triggers an FLR.
For similar reasons, on EF10, in
efx_reset_down(method=RESET_TYPE_MCDI_TIMEOUT), set the number
of active queues to zero before calling efx_stop_all().
And, on farch, in efx_reset_up(method=RESET_TYPE_MCDI_TIMEOUT),
set active_queues and flushes pending & outstanding to zero.
efx_mcdi_mode_{poll,event}() should not take us out of fail-fast
mode. Instead, this is done by efx_mcdi_reset() after the FLR
completes.
The new FLR reset_type RESET_TYPE_MCDI_TIMEOUT doesn't really
fit into the hierarchy of reset 'scopes' whereby efx_reset()
decides some resets subsume others. Thus, it uses separate logic.
Also, fixed up some inconsistency around RESET_TYPE_MC_BIST,
which was in the wrong place in that hierarchy.

over UDP so we use an internal kernel UDP socket to do the
transmits.
These tunnels should behave just like other software devices and
pass the packets on down to the next layer.
Most importantly we want the top-level socket (eg TCP) that created
the traffic to be charged for the SKB memory.
However, once you get into the IP output path, we have code that
assumed that whatever was attached to skb->sk is an IP socket.
To keep the top-level socket being charged for the SKB memory,
whilst satisfying the needs of the IP output path, we now pass in an
explicit 'sk' argument.

The wrong max fw size was being used and causing false
"too big" errors running ethtool -f.

Function qlcnic_setup_tss_rss_intr() might enter endless
loop in case pci_enable_msix() contiguously returns a
positive number of MSI-Xs that could have been allocated.
Besides, the function contains 'err = -EIO;' assignment
that never could be reached. This update fixes the
aforementioned issues.

It's possible to remove the FB tunnel with the command 'ip link del ip6gre0' but
this is unsafe, the module always supposes that this device exists. For example,
ip6gre_tunnel_lookup() may use it unconditionally.
Let's add a rtnl handler for dellink, which will never remove the FB tunnel (we
let ip6gre_destroy_tunnels() do the job).
Introduced by commit c12b395a4664 ("gre: Support GRE over IPv6").

In the dst->output() path for ipv4, the code assumes the skb it has to
transmit is attached to an inet socket, specifically via
ip_mc_output() : The sk_mc_loop() test triggers a WARN_ON() when the
provider of the packet is an AF_PACKET socket.
The dst->output() method gets an additional 'struct sock *sk'
parameter. This needs a cascade of changes so that this parameter can
be propagated from vxlan to final consumer.
Fixes: 8f646c922d55 ("vxlan: keep original skb ownership")

Sometimes when command timeout occurs due to a firmware or
hardware bug, there may be some synchronous commands in command
queue. These commands are never downloaded to firmware causing
hung task warnings. This patch replaces wait_event_interruptible
call with wait_event_interruptible_timeout to fix the issue.

During extended scan, SCAN report event is always followed by
command response. Sometimes It is observed that command response
is processed before SCAN report which leads to a crash, because
current command node is cleared while handling the response.
This patch makes sure that driver's main thread gives priority
to events over command responses.

ip_queue_xmit() assumes the skb it has to transmit is attached to an
inet socket. Commit 31c70d5956fc ("l2tp: keep original skb ownership")
changed l2tp to not change skb ownership and thus broke this assumption.
One fix is to add a new 'struct sock *sk' parameter to ip_queue_xmit(),
so that we do not assume skb->sk points to the socket used by l2tp
tunnel.

The __at86rf230_read_subreg function don't mask and shift register
contents which it should do. This patch adds the necessary masks and
shift operations in this function.
Since we have csma support this can make some trouble on state changes.
Since CSMA support turned on some bits in the TRX_STATUS register that
used to be zero, not masking broke checking of the TRX_STATUS field
after commanding a state change.
