    mac80211: allow releasing driver-buffered frames · 4049e09a
    Johannes Berg authored
    If there are frames for a station buffered in
    the driver, mac80211 announces those in the TIM
    IE but there's no way to release them. Add new
    API to release such frames and use it when the
    station polls for a frame.
    Since the API will soon also be used for uAPSD
    it is easily extensible.
    Note that before this change drivers announcing
    driver-buffered frames in the TIM bit actually
    will respond to a PS-Poll with a potentially
    lower priority frame (if there are any frames
    buffered in mac80211), after this patch a driver
    that hasn't been changed will no longer respond
    at all. This only affects ath9k, which will need
    to be fixed to implement the new API.
