    iwlwifi: mvm: send delba upon rx ba session timeout · 20fc690f
    Naftali Goldstein authored
    When an RX block-ack session times out, the firmware, which offloads
    RX reordering but not the BA session negotiation, stops the session
    but doesn't send a DELBA.  This causes the the session to remain
    active in the remote device, so no more BA sessions will be
    established, causing a severe throughput degradation due to the lack
    of aggregation.
    
    Use the new ieee80211_rx_ba_timer_expired API when the ba session timer
    expires, since this will tear down the ba session and also send a delba.
    
    The previous API used is intended for drivers that offload the
    addba/delba negotiation, but not the rx reordering, while our driver
    does the opposite.
    
    This patch depends on "mac80211: add api to start ba session timer
    expired flow".
