Implement Broadcast/Multicast Integrity Protocol for management frame protection. This patch adds the needed definitions for the new information element (MMIE) and implementation for the new "encryption" type (though, BIP is actually not encrypting data, it provides only integrity protection). These routines will be used by a follow-on patch that enables BIP for multicast/broadcast robust management frames.
