mac80211: send (QoS) Null if no buffered frames
For PS-poll, there's a possible race between us expiring a frame and the station polling for it -- send it a null frame in that case. For uAPSD, the standard says that we have to send a frame in each SP, so send null if we don't have any other frames. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
