2014-05-20ath9k_hw: Abort transmission for sleeping stationRajkumar Manoharan4-3/+31
The data transmission to the power save station should be aborted immediately, whenever the station informs sleep state. Right now the frames queued into into hardware are being transmitted until the hardware detects the power save station based excessive retries of the data frames due to unacknowlegdement. Then remaining frames are returned with filetered status and might be retried later by driver or mac80211. Per WFA certification testing, AP should not send out more than two frames after processing nullfunc with PM bit set from associated station. To speed up tx filtering, the pending frames in hardware queues for given station will be aborted immediately via tx filter registers. This transmit filters can be ignored if the descriptor is having invalid destination index or clear destination mask set.
