The main requirements: - support CCMP encryption/decryption of unicast robust management frames (subset of Action frames, Deauthentication, Disassociation) - support BIP and IGTK configuration for group addressed robust management frames (TX-only for AP, RX-only for STA); I would expect most drivers to use software implementation on the host CPU for this taken into account that there is only very limited use of group addressed robust management frames - SA Query mechanism (mac80211-based drivers get this pretty much automatically from hostapd for AP mode and mac80211 for STA) - ability to configure RSN capabilities into RSN element and to provide the received element to user space (again, most mac80211-based drivers should work as-is) -- Jouni Malinen PGP id EFC895FA
