- 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.

- mac80211: fix CSA tx queue stopping
-
- It was possible for tx queues to be stuck stopped
- if AP CSA finalization failed. In that case
- neither stop_ap nor do_stop woke the queues up.
- This means it was impossible to perform tx at all
- until driver was reloaded or a successful CSA was
- performed later.
-
- It was possible to solve this in a simpler manner
- however this is more robust and future proof
- (having multi-vif CSA in mind).
-
- New sdata->csa_block_tx is introduced to keep
- track of which interfaces requested tx to be
- blocked for CSA. This is required because mac80211
- stops all tx queues for that purpose. This means
- queues must be awoken only when last tx-blocking
- CSA interface is finished.
-
- It is still possible to have tx queues stopped
- after CSA failure but as soon as offending
- interfaces are stopped from userspace (stop_ap or
- ifdown) tx queues are woken up properly.

+ 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.
