    mac80211: don't react to beacon loss if HW monitoring · 7eeff74c
    Johannes Berg authored
    If the HW is monitoring connection loss (as advertised
    by IEEE80211_HW_CONNECTION_MONITOR) but not filtering
    beacons (IEEE80211_VIF_BEACON_FILTER) then mac80211 will
    still start the beacon loss timer and if a few beacons
    are lost, e.g. due to scanning, drop the connection.
    
    If the hardware doesn't advertise connection monitoring,
    then it won't drop the connection right away but probe
    the AP, which is intended, but due to the logic in the
    timer when connection monitoring is done it assumes the
    connection was actually lost.
    
    Fix this problem by not starting the timer when the HW
    does connection monitoring.
