    mac80211: close the SP when we enqueue frames during the SP · f6d4671a
    Emmanuel Grumbach authored Mar 17, 2016
    
    
    Since we enqueued the frame that was supposed to be sent
    during the SP, and that frame may very well cary the
    IEEE80211_TX_STATUS_EOSP bit, we may never close the SP
    (WLAN_STA_SP will never be cleared). If that happens, we
    will not open any new SP and will never respond to any poll
    frame from the client.
    Clear WLAN_STA_SP manually if a frame that was polled during
    the SP is queued because of a starting A-MPDU session. The
    client may not see the EOSP bit, but it will at least be
    able to poll new frames in another SP.
