[PATCH v2] mac80211: add support for userspace to handle auth frames on adhoc ifaces

[Will Hawkins <hawkinsw@xxxxxxxxxxxxxxxxxxxxx>]

Allow userspace daemons to register for (DE)AUTH management frames
received on an adhoc interface. Registration for these frames, done
through nl80211, is necessary to support certain userspace
authentication schemes.
