When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.
This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.

This is iwlegacy version of:
commit 342bbf3fee2fa9a18147e74b2e3c4229a4564912
Author: Johannes Berg <johannes.berg@intel.com>
Date: Sun Mar 4 08:50:46 2012 -0800
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

On rt2x00_dmastart() we increase index specified by Q_INDEX and on
rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. So entries
between Q_INDEX_DONE and Q_INDEX are those we currently process in the
hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can
submit to the hardware.
According to that fix rt2x00usb_kick_queue(), as we need to submit RX
entries that are not processed by the hardware. It worked before only
for empty queue, otherwise was broken.
Note that for TX queues indexes ordering are ok. We need to kick entries
that have filled skb, but was not submitted to the hardware, i.e.
started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set.
From practical standpoint this fixes RX queue stall, usually reproducible
in AP mode, like for example reported here:

As we don't provide custom regulatory rules to cfg80211,
"chan->max_power" remains uninitialized (0dbm) and
"chan->max_reg_power" will contain maximum power for a channel
extracted from regulatory rules provided by CRDA; hence use
"chan->max_reg_power" in reg_notifier handler instead of
"chan->max_power" to set max_power in firmware.

We miss to wakeup main thread after adding command to cmd pending
queue at follwing places. These commands are handled later when
main thread is woken up for handling an interrupt for sleep event
from firmware. This adds worst case delay of 50msec.
1) We don't wakeup main thread when asynchronous command is added
to cmd pending queue. Move queue_work() call from
mwifiex_wait_queue_complete() to mwifiex_send_cmd_async() to wakeup
main thread for sync as well as async commands.
2) Scan operation is triggered due to following reasons
a) request from user (ex. "iw scan" command)
b) Scan performed by driver internally.
In first case main thread is woken up when first scan command is
queued in cmd pending queue (we don't need to wakeup main thread for
subsequent scan commands, because they are queued in scan command
response handler), but it is not done for second case. queue_work()
is moved inside mwifiex_scan_networks() to handle both the cases.

ath9k_ani_reset (which is called at reset time) uses a state variable
ani->update_ani to prevent the ANI noise immunity state on the operating
channel from being overwritten by background scans. Unfortunately this
is also being set for AP mode, since it's mixed with code that is only
supposed to change the default settings after a reset.
In AP mode this has the side effect of having ANI run, but being unable to
change its runtime noise immunity level, making it effectively useless.
Fix this by getting rid of ani->update_ani and passing a parameter to
ath9k_hw_set_ofdm_nil and ath9k_hw_set_cck_nil instead.

Every now and then, after resuming from suspend, the iwlegacy driver
prints
iwl4965 0000:03:00.0: Queue 2 stuck for 2000 ms.
iwl4965 0000:03:00.0: On demand firmware reload
I have no idea what causes these errors. But the code currently uses
wd_timeout in the first error. wd_timeout will generally be set at
IL_DEF_WD_TIMEOUT (ie, 2000). Perhaps printing for how long the queue
was actually stuck can clarify the cause of these errors.

mac80211 adds stations in HT IBSS as soon as a frame comes by,
even if the HT capabilities are not known yet (they are often
received later, e.g. in beacons). So far, ampdu factor/density
are only calculated when the station is initially added.
This patch changes this to update ampdu factor/density settings
when starting a blockack session.
Using this patch, we had performance boosts from 60 to 150 MBit/s
between two 2x2 Atheros devices in 5 GHz HT IBSS mode.

The cause is due to calling kfree_skb() with interrupts disabled.
This bug is discussed in https://bugzilla.redhat.com/show_bug.cgi?id=797709.

As recovery queuing can now occur from multiple code paths
it's convenient to know what triggered it in all cases
other than an intended recovery which is part of the
switch between single role to multi role.

Following the addition of propagating errors from the bus ops
there's a need to distinguish between bus errors (including timeout)
and a legitimate timeout occuring in cmd_wait_for_event_or_timeout.
In case of real bus errors we need to queue recovery even in cases
where a timeout on a response from the FW to a command is acceptable.

commit 14bba17b "wl12xx: Propagate errors from wl1271_raw_write32"
breaks down TX in certain scenarios. wl1271_irq_locked() propagates
errors from wl1271_tx_work_locked however it may return -EBUSY
when the FW queues are full which is a legitimate case and not a
a real error. In this case a recovery is triggered by wl1271_irq
and this keeps repeating itself so TX is completely broken.
Fix it by avoiding propagating return values as errors even if they
aren't. Only bus (SDIO or SPI) ops failures would be progagated
as only these should trigger recovery.

We need to release the IRQ if hw_info() or identify_chip() fails. And
we need unregister the HW with mac80211 if there are any failures
after it's registered.

The new PG2 version of the chip has a few differences in terms of FW
API if compared to PG1. PG1 is just a sample that shouldn't be used
in real life, so to avoid having to handle both separately, mark the
PG1 version as deprecated and bail out during probe.

When authentication/association timed out, the driver would
complain bitterly, printing the message
ACTIVATE a non DRIVER active station id ... addr ...
The cause turns out to be that when the AP station is added
but we don't associate, the IWL_STA_UCODE_INPROGRESS is set
but never cleared. This then causes iwl_restore_stations()
to attempt to resend it because it uses the flag internally
and uploads even if it didn't set it itself.
To fix this issue and not upload the station again when it
has already been removed by mac80211, clear the flag after
adding it in case we add it only for association.

Mainline build reports:
warning: (WL12XX) selects WLCORE which has unmet direct dependencies (NETDEVICES && WLAN && WL_TI && GENERIC_HARDIRQS && MAC80211 && INET)
The INET dependency was added in commit
3c6af5b54fe74b6e56efadc22927e4055d00e9fc:
wl1271_main.c:(.text+0x271052): undefined reference to `unregister_inetaddr_
notifier'
wl1271_main.c:(.text+0x2714d7): undefined reference to `register_inetaddr_no
tifier'
Driver is doing some filtering based on IP addresses...
but this driver no longer has that code and it builds fine even when
CONFIG_INET is not enabled, so drop that dependency and eliminate the
kconfig warning message.

commit 7a532fe7131216a02c81a6c1b1f8632da1195a58
ath9k_hw: fix interpretation of the rx KeyMiss flag
This commit used the rx key miss indication to detect packets that were
passed from the hardware without being decrypted, however it seems that
this bit is not only undefined in the static WEP case, but also for
dynamically allocated WEP keys. This caused a regression when using
WEP-LEAP.
This patch fixes the regression by keeping track of which key indexes
refer to CCMP keys and only using the key miss indication for those.

The code is fine in both cases as-is, but we can
write it slightly differently to fix smatch/sparse
complaints:
* compare the skb pointer (which we use as a cookie)
by casting the skb to unsigned long rather than the
cookie to a pointer (fixes "different address spaces")
* when transmitting, data->channel must be assigned,
don't check it (fixes "dereferenced before check")

Take the mutex early in the resume handler and use the locked version of
the IRQ routine. This ensures any recoveries queued will only take place
after resume has fully completed.

Separate the threaded IRQ handling routine into two functions.
The outer function takes the mutex and calls recovery on errors. It also
performs a Tx-path optimization to avoid redundant works.
The inner function is simplified - all calls to recovery are removed and
it assumes the lock is taken. The locked variant will be reused elsewhere.

If an error is detected after mac80211 is already suspended, the recovery
work will not be queued. This will leave the driver in a bad state on
resume.
Detect this in the resume op and re-queue a recovery.
