ath9k_hw: fix PLL clock initialization for newer SoC
On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL
register changed. This currently breaks at least 5/10 MHz operation.
AR933x uses the old layout.
It might also have been causing other stability issues because of the
different location of the PLL_BYPASS bit which needs to be set during
PLL clock initialization.
This patch also removes more instances of hardcoded register values in
favor of properly computed ones with the PLL_BYPASS bit added.

ath9k_hw: reduce ANI spur immunity setting on HT40 extension channel
The cycpwr_thr1 value needs to be lower on the extension channel than on
the control channel, similar to how the register settings are programmed
in the initvals.
Also drop the unnecessary check for HT40 - this register can always be
written. This patch has been reported to improve HT40 stability and
throughput in some environments.

When bringing down the AP, a WARN_ON is hit because the bss config chandef

Since AP_VLAN channel settings do not matter for anything chanctx related
(always inherits the settings from the AP interface), let's just ignore

ath9k: fix aggregation session lockup
If an aggregation session fails, frames still end up in the driver queue
with IEEE80211_TX_CTL_AMPDU set.
This causes tx for the affected station/tid to stall, since
ath_tx_get_tid_subframe returning packets to send.
Fix this by clearing IEEE80211_TX_CTL_AMPDU as long as no aggregation
session is running.

ath9k: fix pending tx frames accounting
Packets originally buffered for the regular hardware tx queues can end
up being transmitted through the U-APSD queue (via PS-Poll or U-APSD).
When packets are dropped due to retransmit failures, the pending frames
counter is not always updated properly.
Fix this by keeping track of the queue that a frame was accounted for in
the ath_frame_info struct, and using that on completion to decide
whether the counter should be updated.
This fixes some spurious transmit queue hangs.

mac80211: use csa counter offsets instead of csa_active
vif->csa_active is protected by mutexes only. This
means it is unreliable to depend on it on codeflow
in non-sleepable beacon and CSA code. There was no
guarantee to have vif->csa_active update be
visible before beacons are updated on SMP systems.
Using csa counter offsets which are embedded in

RCU assignment) is much safer.

To avoid the issue, setup beaconing dynamically by configuring offsets

which limit number of beacons that hardware will try to send.

mac80211: fix station/driver powersave race
It is currently possible to have a race due to the station PS
unblock work like this:
* station goes to sleep with frames buffered in the driver
* driver blocks wakeup
* station wakes up again
* driver flushes/returns frames, and unblocks, which schedules
the unblock work
* unblock work starts to run, and checks that the station is
awake (i.e. that the WLAN_STA_PS_STA flag isn't set)
* we process a received frame with PM=1, setting the flag again
* ieee80211_sta_ps_deliver_wakeup() runs, delivering all frames
to the driver, and then clearing the WLAN_STA_PS_DRIVER and
WLAN_STA_PS_STA flags
In this scenario, mac80211 will think that the station is awake,
while it really is asleep, and any TX'ed frames should be filtered
by the device (it will know that the station is sleeping) but then
passed to mac80211 again, which will not buffer it either as it
thinks the station is awake, and eventually the packets will be
dropped.
Fix this by moving the clearing of the flags to exactly where we
learn about the situation. This creates a problem of reordering,
so introduce another flag indicating that delivery is being done,
this new flag also queues frames and is cleared only while the
spinlock is held (which the queuing code also holds) so that any
concurrent delivery/TX is handled correctly.

mac80211: reduce packet loss notifications under load
During strong signal fluctuations under high throughput, few consecutive
failed A-MPDU transmissions can easily trigger packet loss notification,
and thus (in AP mode) client disconnection.
Reduce the number of false positives by checking the A-MPDU status flag
and treating a failed A-MPDU as a single packet.

ath9k: avoid passing buffers to the hardware during flush
The commit "ath9k: fix possible hang on flush" changed the receive code
to always link rx descriptors of processed frames, even when flushing.
In some cases, this leads to flushed rx buffers being passed to the
hardware while rx is already stopped.
