    mac80211: explicitly notify drivers of frame release · 40b96408
    Johannes Berg authored
    iwlwifi needs to know the number of frames that are
    going to be sent to a station while it is asleep so
    it can properly handle the uCode blocking of that
    station.
    
    Before uAPSD, we got by by telling the device that
    a single frame was going to be released whenever we
    encountered IEEE80211_TX_CTL_POLL_RESPONSE. With
    uAPSD, however, that is no longer possible since
    there could be more than a single frame.
    
    To support this model, add a new callback to notify
    drivers when frames are going to be released.
