Subject: iwlwifi: fix length check in multi-TB HCMD

As reported by Ben Hutchings, there was a harmless issue in
the checks being done on the lengths of the TBs while
building the TFD for a multi-TB host command.

We didn't update the internal of the PCIe transport when
we read the RFkill state directly. Fix that.

Subject: iwlwifi: dvm: don't send HCMD in restart flow

There is a race between the restart flow and the workers.
The workers are cancelled after the fw is already killed
and might send HCMD when there is fw to handle them.
Simply check that there is a fw to which the HCMD can be
sent before actually sending it.

Subject: mwifiex: reset skb->data after processing PCIe sleep confirm cmd
 respose

This patch is a bug fix for an issue wherein power save was not
working for PCIe. This happens because for processing power save
sleep confirm command we pull skb so that skb->data points ahead
of interface header. We use same skb to get other cmda responses
as well. So if we don't push skb after processing cmd response,
it results into reduction in skb->len and finally skb->len reaches
zero. This causes failure in processing sleep command response.
Fix this by pushing skb by INTF_HEADER_LEN at the end of command
response processing.

Subject: b43: N-PHY: increase initial value of "mind" in RSSI calibration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We're using "mind" variable to find the VCM that got the best polling
results. For each VCM we calculte "currd" which is compared to the
"mind". For PHY rev3+ "currd" gets values around 14k-40k. Looking for a
value smaller than 40 makes no sense, so increase the initial value.

This fixes a regression introduced in 3.4 by commit:
e0c9a0219a8f542e3946fe972a68aacf8c3f906c
(my BCM4322 performance dropped from 18,4Mb/s to 9,26Mb/s)

Subject: b43: A fix for DMA transmission sequence errors

Intermittently, b43 will report "Out of order TX status report on DMA ring".
When this happens, the driver must be reset before communication can resume.
The cause of the problem is believed to be an error in the closed-source
firmware; however, all versions of the firmware are affected.

This change uses the observation that the expected status is always 2 less
than the observed value, and supplies a fake status report to skip one
header/data pair.

Not all devices suffer from this problem, but it can occur several times
per second under heavy load. As each occurence kills the unmodified driver,
this patch makes if possible for the affected devices to function. The patch
logs only the first instance of the reset operation to prevent spamming
the logs.

il4965_rs_initialize_lq checks to see if sta is null, however, before that
check il4965_rs_use_green dereferences sta when intializing use_green.
Avoid a potential null pointer dereference error by only calling
il4965_rs_use_green after we are sure sta is not null.

Subject: b43: N-PHY: use more bits for offset in RSSI calibration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When calculating "offset" for final RSSI calibration we're using numbers
bigger than s8 can hold. We have for example:
offset[j] = 232 - poll_results[j];
formula. If poll_results[j] is small enough (it usually is) we treat
number's bit as a sign bit. For example 232 - 1 becomes:
0xE8 - 0x1 = 0xE7, which is not 231 but -25.

This code was introduced in e0c9a0219a8f542e3946fe972a68aacf8c3f906c
and caused stability regression on some cards, for ex. BCM4322.

Subject: iwlwifi: dvm: fix the passive-no-RX workaround

Alex Romosan reported that since the mac80211 changes in
"mac80211: start auth/assoc timeout on frame status" and
the subsequent fixes in "mac80211: fix auth/assoc timeout
handling" (commits 1672c0e31917 and 89afe614c0c) there's
sometimes an issue connecting to a 5 GHz network with the
iwlwifi DVM driver.

The reason appears to be that since these commits any bad
TX status makes mac80211 immediately try again, causing
all of the authentication attempts to be quickly rejected
by the firmware as it hasn't heard a beacon yet. Before,
it would wait for the timeout regardless of status.

To fix this, invoke the passive-no-RX workaround when not
associated yet as well. This will cause the first frame
to get lost, but then the driver will stop the queues and
the second attempt will only be transmitted after hearing
a beacon, thus delaying it appropriately to not make the
firmware reject it again.

tx and rx michael tkip keys are always swapped in case being
configured per mac. This is wrong for AP. The swap should only
be done for STA mode.

ath_complete_reset will not be called if ath9k_hw_reset

balence the previous ath_prepare_reset call.  Also schedule a
reset as a best effort method to recover the chip from
whatever state caused the channel change failure.

It appears that when this register read fails it never recovers, so
I think there is no need to repeat the same error message ad infinitum.

Subject: rt2x00: rt2x00pci: fix build error on Ralink RT3x5x SoCs

The rt2800pci driver supports the built-in wireless
MAC of the Ralink RT3x5x SoCs. However building the
driver for these SoCs leads to the following error:

    LD      init/built-in.o
  drivers/built-in.o: In function `rt2800pci_rxdone_tasklet':
  <...>/drivers/net/wireless/rt2x00/rt2800pci.c:1012: undefined reference to `rt2x00pci_rxdone'
  drivers/built-in.o:(.rodata+0x4780): undefined reference to `rt2x00pci_initialize'
  drivers/built-in.o:(.rodata+0x4784): undefined reference to `rt2x00pci_uninitialize'
  drivers/built-in.o:(.rodata+0x47bc): undefined reference to `rt2x00pci_flush_queue'
  drivers/built-in.o:(.rodata+0x4818): undefined reference to `rt2x00pci_regbusy_read'
  make[5]: *** [vmlinux] Error 1

The missing functions are provided by the rt2x00pci
module. This module is only selected by the rt2800pci
driver if PCI support is enabled in the kernel, because
some parts of the rt2x00pci code depends on PCI support.

PCI support is not available on the RT3x5x SoCs because
those have no PCI host controller at all.

Move the non PCI specific code from rt2x00pci into a
separate module. This makes it possible to use that
code even if PCI support is disabled. The affected
functions are used by all of the rt2x00 PCI drivers
so select the new module for those drivers.
