When a station is asleep, the fw will set it as "asleep". All queues that are used only by one station will be stopped by the fw. In pre-DQA mode this was relevant for aggregation queues. However, in DQA mode a queue is owned by one station only, so all queues will be stopped. As a result, we don't expect to get filtered frames back to mac80211 and don't have to maintain the entire pending_frames state logic, the same way as we do in aggregations. The correct behavior is to align DQA behavior with the aggregation queue behaviour pre-DQA: - Don't count pending frames. - Let mac80211 know we have frames in these queues so that it can properly handle trigger frames. When a trigger frame is received, mac80211 tells the driver to send frames from the queues using release_buffered_frames. The driver will tell the fw to let frames out even if the station is asleep. This is done by iwl_mvm_sta_modify_sleep_tx_count.
