    mac80211: disconnect when user changes channel · 7e9debe9
    Johannes Berg authored
    If we do not disconnect when a channel switch is requested,
    we end up eventually detection beacon loss from the AP and
    then disconnecting, without ever really telling the AP, so
    we might just as well disconnect right away.
    
    Additionally, this fixes a problem with iwlwifi where the
    driver will clear some internal state on channel changes
    like this and then get confused when we actually go clear
    that state from mac80211.
    
    It may look like this patch drops the no-IBSS check, but
    that is already handled by cfg80211 in the wext handler it
    provides for IBSS (cfg80211_ibss_wext_siwfreq).
