    mac80211: recalculate min channel width on VHT opmode changes · d2941df8
    Johannes Berg authored
    When an associated station changes its VHT operating mode this
    can/will affect the bandwidth it's using, and consequently we
    must recalculate the minimum bandwidth we need to use. Failure
    to do so can lead to one of two scenarios:
     1) we use a too high bandwidth, this is benign
     2) we use a too narrow bandwidth, causing rate control and
        actual PHY configuration to be out of sync, which can in
        turn cause problems/crashes
