+ 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.
