As far as mac80211 is concerned, I think the patch is not needed.
mac80211 has done what it needed to do through the SIOC{S/G}IWAUTH
interface.
It seems the fix should be in userspace app, iwconfig should use the
SIOC{S/G}IWAUTH interface and resort to IW_ENCODE_RESTRICTED if it wants
to maintain the compatibility with old drivers.
