* Added new action category IEEE80211_ACTION_CAT_SELF_PROT which is used by 11s for Mesh Peering Management; * Updated Self protected enum Action codes to start from 1 instead of 0 according to the standard spec; * Removed old and wrong action categories IEEE80211_ACTION_CAT_MESHPEERING; * Modified ieee80211_mesh.c and ieee80211_action.c to use the new action category code; * Added earlier verification code in ieee80211_input; Approved by: adrian
