From 5f0dd296a01c8173fcc05a8b262a1168ae90bc74 Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Wed, 6 Jul 2011 23:00:21 +0200 Subject: rt2x00: Implement tx_frames_pending mac80211 callback function. 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.
