Subject: [PATCH] mac80211: un-schedule TXQs on powersave start
|
|
|
|
Once a station enters powersave, its queues should not be returned by
|
|
ieee80211_next_txq() anymore. They will be re-scheduled again after the
|
|
station has woken up again
|
|
|
|
Fixes: 1866760096bf4 ("mac80211: Add TXQ scheduling API")
