    mac80211: explicitly copy channels to VLANs where needed · 1f4ac5a6
    Johannes Berg authored
    Currently the code assigns channel contexts to VLANs
    (for use by the TX/RX code) when the AP master gets
    its channel context assigned. This works fine, but
    in the upcoming radar detection work the VLANs don't
    require a channel context (during radar detection)
    and assigning one to them anyway causes issues with
    locking and also inconsistencies -- a VLAN interface
    that is added before radar detection would get the
    channel context, while one added during it wouldn't.
    Fix these issues moving the channel context copying
    to a new explicit operation that will not be used
    in the radar detection code.
