If userspace requested control port frames to go over 80211, then do so. The control packets are intercepted just prior to delivery of the packet to the underlying network device. Pre-authentication type frames (protocol: 0x88c7) are also forwarded over nl80211. Signed-off-by: Denis Kenzior <denkenz@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
