Subject: [PATCH] cfg80211: disallow configuring unsupported interfaces

In order to force drivers to advertise their interface
types, don't just disallow creating new interfaces with
unadvertised types but also disallow setting them UP.
Additionally, add some validation on the operations the
drivers support.
