      iwlwifi: mvm: cleanup pending frames in DQA mode · 9a3fcf91
      Sara Sharon 提交于
      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.
