    mac80211: set HT channel before association · 24398e39
    Johannes Berg authored
    Changing the channel type during operation is
    confusing to some drivers and will be hard to
    handle in multi-channel scenarios. Instead of
    changing the channel, set it to the right HT
    channel before authenticating/associating and
    don't change it -- just update the 20/40 MHz
    restrictions in rate control as needed when
    changed by the AP.
    This also fixes a problem that Paul missed in
    his fix for the "regulatory makes us deaf"
    issue -- when we couldn't use 40 MHz we still
    associated saying we were using 40 MHz, which
    could in similarly broken APs make us never
    even connect successfully.
