mac80211: allow CSA to self with immediate quiet
Currently, due to some buggy APs that continue to include CSA IEs after the switch, we ignore CSA to same channel. However, some other APs may do CSA to self in order to have immediate quiet. Allow it. Do it only for beacons. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
