Implementing this callback function will cause mac80211 refrain from going to powersave state when there are still untransmitted TX frames in the queues. This would exactly mimic the behaviour of the legacy vendor driver which also doesn't go in powersave mode if there are still TX frames that are not transmitted. This should make powersaving and rt2x00 a better couple. Signed-off-by: Gertjan van Wingerde Acked-by: Helmut Schaa Signed-off-by: Ivo van Doorn Signed-off-by: John W.
