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.
|
|
