ath9k_hw: Improve fast channel change for AR9003 chips

In order to reduce the overall scan time, fast channel change
should be implemented properly. This patch adds fast channel
change support across band switch or channel mode switch
instead of doing full chip reset. During the fastcc, tx iqcal
measurements are preserved and will be reloaded after successful
the channel change.

This patch also addressed fast channel issue where the STA can not
see APs in higher than operating channel on 5GHz band after
the association.

mwifiex: use separate wait condition for each command node

Currently global wait condition (adapter->cmd_wait_q.condition)
is used while sending synchronous commands to FW. When two threads
enter in mwifiex_send_cmd_sync() routine at the same time, both the
threads wait for their command responses. Since wait condition is
same for both, they wake up simultaneously after getting response
of 1st command. After this when a thread is waiting for command
response of 3rd command, it wakes up after getting response of 2nd
command and so on. Therefore we don't wait for the response of last
command(0xaa) during unload. Hence while next time loading the driver
command time out is seen for INIT command.

This problem is resolved by having separate wait condition flag for
each command(except scan command). Since scan command is treated
differently (by maintaining scan pending q etc.), newly defined flag
(scan_wait_q_woken) is used as a scan wait condition.

While inspecting the code, I saw that iwl_tx_queue_unmap modifies

that it can race with the reclaim flow. This can possibly lead to
a DMA warning complaining that we unmap the same buffer twice.

This is more a W/A than a fix since it is really weird to take
sta_lock inside iwl_tx_queue_unmap, but it can help until we revamp

iwlagn: stop interrupts when suspending

Occasionally, the device will send interrupts
while it is resuming, at a point where we are
not set up again to handle them. This causes
the core IRQ handling to completely disable
the IRQ, and then the driver won't work again
until it is reloaded/rebound.

To fix this issue disable the IRQ on suspend,
this will cause us to only get interrupts
again after we've setup everything on resume.

iwlagn: update beacon smarter

Updating the beacon every time right after one was
transmitted is pointless, most of the time we might
not even have to update it. We will update it every
time it changes, which includes from set_tim(), a
callback iwlwifi didn't implement so far.

This also reduces latency for clients, previously
we would update the beacon right after the previous
one was transmitted, and then a TIM change would
only take effect after that again -- updating the
beacon right after the TIM changes makes the TIM
change go out to the air faster.

ath9k_hw: fix a regression in key miss handling

The commit "ath9k_hw: Fix incorrect key_miss handling" changed the code
to only report key miss errors if a MIC error wasn't reported.
When checking the flags in that order in the MAC code, it might miss some
real events, because the value of the MIC error flag is undefined under
some conditions.

The primary issue addressed by the previous commit is making sure that
MIC errors are properly reported on the STA side. This can be fixed in
a better way by adding a separate rx status flag for key miss and
ignoring it for multicast frames.

This fix slightly improves stability in AP mode on some older hardware,
like AR9132.

ath9k_hw: clean up tx power handling

The code for handling various restrictions concerning regulatory limits,

EEPROM parsing implementations, making it hard to review.

This patch partially cleans up the mess by unifying regulatory limit
handling in one function and simplifying handling of antenna gain.
It also removes unused transmit power scaling arrays from the EEPROM code,
which belonged to an unimplemented API that isn't supposed to be in
the driver anyway.

PHY errors relevant for ANI are always tracked by hardware counters, the

mac80211: dont orphan TX skb

This was another workaround for truesize "bugs".
The reason we did this was that when we orphaned
the SKB it wouldn't be truesize-checked later.
Now that the check is gone (and we just charge
the former smaller size to the socket) there's
no longer a reason to orphan the skb here.

Keep the skb charged to the socket until it is
really freed (or orphaned in TX status). This
helps flow control and allows us to get at the
socket later for other purposes.

mac80211: dont adjust truesize

There's no need to adjust truesize.

The history of this was that we always ran into

skb_truesize_check() checked that truesize was
bigger or equal to the actual allocation, which
would trigger in mac80211 due to header adding.
The check no longer exists and we shouldn't be
messing with the truesize anwyay.
