mac80211: 802.11w - Add BIP (AES-128-CMAC) 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.

mac80211: aes-cmac: switch to shash CMAC driver Instead of open coding the CMAC algorithm in the mac80211 driver using byte wide xors and calls into the crypto layer for each block of data, instantiate a cmac(aes) synchronous hash and pass all the data into it directly. This does not only simplify the code, it also allows the use of more efficient and more secure implementations, especially on platforms where SIMD ciphers have a considerable setup cost.
