Hi Jouni,

Good point. The P2P interface address and P2P device address only need 
to be different if one would want to do P2P management and have a group 
connection concurrently (correct me if I am wrong here, maybe it is a 
restriction for brcm firmware only) so the check seems a bit too 
restrictive.

Regards,
Arend
