-Subject: [PATCH] ath9k: improve powersave filter handling
-
-For non-aggregated frames, ath9k was leaving handling of powersave
-filtered packets to mac80211. This can be too slow if the intermediate
-queue is already filled with packets and mac80211 does not immediately
-send a new packet via drv_tx().
-
-Improve response time with filtered frames by triggering clearing the
-powersave filter internally.
