mac80211: update mesh peering frame codes
Have the mesh peering frames use the self-protected action and reason codes specified in 802.11s and defined in ieee80211.h. Remove the local enums. Signed-off-by: Thomas Pedersen <thomas@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
