Flashing some of the PHYs can take longer thus increasing the total flash
update time to a max of 40s.

The rx_drops_no_frags HW counter for RSS rings is 16bits in HW and can
wraparound often. Maintain a 32-bit accumulator in the driver to prevent
frequent wraparound.
Also, incorporated Eric's feedback to use ACCESS_ONCE() for the accumulator
write.

There is a possibility of be_post_rx_frags() being called simultaneously from
both be_worker() (when rx_post_starved) and be_poll_rx() (when rxq->used is 0).
This can be avoided by posting rx buffers only when some completions have been
reaped.

ath6kl is now in drivers/net/wireless/ath so the staging driver
is not supported anymore and should be removed.

Instead of maintaining static scan table in driver, scan list is sent
to cfg80211 stack (after parsing each scan command response).
In assoc handler (for infra and ibss network) requested BSS information
is retrieved using cfg80211_get_bss() API.
With the changes above some redundant code are removed.

If the driver gets a tx status report for an A-MPDU sent to a station that
just went to sleep, that leaves a race condition where this tx status can
trigger another A-MPDU transmission.
To fix this, check if the station is sleeping before queueing the tid.

ath9k_hw_4k_get_eeprom() overrides the eeprom value for txgain if the
minor version is not 19 or above with a value of 0.
ar9002_hw_init_mode_gain_regs() relies on this information to
determine whether this is a high power wifi card or not. The override
caused the driver to always use the 'normal' power tables even for
high power devices if their minor version was not high enough. Thus
leading to reduced power output.
This isn't needed for the AR9285; the check originated with the
AR9280 setup code which requires the EEPROM version check.

RX_FLAG_HT must be included when reporting MCS rates. Without
this, mac80211 ended up dropping any frame sent at MCS index 12
or higher and that resulted in oddly random looking errors in
mac80211_hwsim tests.

Sometimes, the network manager is failing to connect to the AP due
to the below kernel crash message. The reason behind this,
after issuing the connect command to the chip, the chip is sending
disconnect event and then immediately one connect event to the host
in some random cases.
The host driver resets all states (including cfg80211 state machine)
when it receives disconnect event from the chip. But, still the host
driver reports the next received connect event to cfg80211, at that time
cfg80211 SME state would have been in IDLE state, which was causing
the below kernel crash.
Now, host driver's sme state machine is checked every time before
delivering connect event to cfg80211

When ath6kl module was removed while a scan was ongoing the driver would
crash in ath6kl_cfg80211_scan_complete_event().
Fix the function not to iterate nodes when the scan is aborted. The nodes
are already freed when the module is being unloaded. This patch removes the
null check entirely as the wmi structure is not accessed anymore during
module unload.
Also fix a bug where the status was checked as a bitfield with '&' operator.
But it's not a bitfield, just a regular error code.
This is a port of my patch from ath6kl staging with the same title.

ath6kl_cfg80211_scan_node() was calling cfg80211_inform_bss_frame()
with CFP_KERNEL but the function is executed with a spin lock taken.
This is wrong and the function must use GFP_ATOMIC instead.

In my setup data transfer stalls when there's data transmission during
scan. After some testing I found out that using background scan
when connected to makes the problem go away. This is more like
a workaround than a proper fix, but as the stall is so severe the
workaround is justified.
With a dual band card this increases scan time when connected from
1.9s to 4.4s. When not connected the scan time is not affected and
is the same 1.9s.
