-Subject: [PATCH] mac80211: make ieee80211_schedule_txq schedule empty TXQs
-
-Currently there is no way for the driver to signal to mac80211 that it should
-schedule a TXQ even if there are no packets on the mac80211 part of that queue.
-This is problematic if the driver has an internal retry queue to deal with
-software A-MPDU retry.
-
-This patch changes the behavior of ieee80211_schedule_txq to always schedule
-the queue, as its only user (ath9k) seems to expect such behavior already:
-it calls this function on tx status and on powersave wakeup whenever its
-internal retry queue is not empty.
-
-Also add an extra argument to ieee80211_return_txq to get the same behavior.
-
-This fixes an issue on ath9k where tx queues with packets to retry (and no
-new packets in mac80211) would not get serviced.
-
-Fixes: 89cea7493a346 ("ath9k: Switch to mac80211 TXQ scheduling and airtime APIs")
