cfg80211: disallow interfering with stations on non-AP (part 2)
On non-AP interfaces userspace has no business interfering with the station management, this can confuse mac80211 (and other drivers probably wouldn't support it anyway). Allow adding and removing stations only on AP interfaces. (Reconcile this w/ previous version of patch posted with same subject... -- JWL) Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
