cfg80211: allow changing port control protocol
Some vendor specified mechanisms for 802.1X-style
functionality use a different protocol than EAP
(even if EAP is vendor-extensible). Allow setting
the ethertype for the protocol when a driver has
support for this. The default if unspecified is
EAP, of course.
Note: This is suitable only for station mode, not
for AP implementation.
