    cfg80211: Enable GO operation on additional channels · 174e0cd2
    Ilan Peer authored
    Allow GO operation on a channel marked with IEEE80211_CHAN_GO_CONCURRENT
    iff there is an active station interface that is associated to
    an AP operating on the same channel in the 2 GHz band or the same UNII band
    (in the 5 GHz band). This relaxation is not allowed if the channel is
    marked with IEEE80211_CHAN_RADAR.
    Note that this is a permissive approach to the FCC definitions,
    that require a clear assessment that the device operating the AP is
    an authorized master, i.e., with radar detection and DFS capabilities.
    It is assumed that such restrictions are enforced by user space.
    Furthermore, it is assumed, that if the conditions that allowed for
    the operation of the GO on such a channel change, i.e., the station
    interface disconnected from the AP, it is the responsibility of user
    space to evacuate the GO from the channel.
