mac80211: Robust Action frame categories for MFP
IEEE 802.11w/D9.0 introduces a mechanism for Action field Category values to be used to select which Action frames are Robust. Public and Vendor-specific categories are marked as not Robust in IEEE 802.11w; HT will be marked not Robust in IEEE 802.11n. A new Vendor-specific Protected category is allocated for Robust vendor-specific Action frames. Another new category, Protected Dual of Action, is introduced for protecting some existing Public Action frames (e.g., IEEE 802.11y protected enablement).
