Add ccm(aes) implementation from linux-wireless mailing list (see
http://permalink.gmane.org/gmane.linux.kernel.wireless.general/126679).
This eliminates FPU context store/restore overhead existing in more
general ccm_base(ctr(aes-aesni),aes-aesni) case in MAC calculation.
Convert this patch to new AEAD API.

I've been using this patch or something similar for a while and it
significantly helps me with sw-crypt performance. One version or another
has been around the internet for some time, and I am not the originator
of this code, but would still be happy to see it upstream if someone
can review and bless it.
No. I don't think this will ever fly by the crypto folks in this
form due to the CRYPTO_ALGO_ASYNC fallback parts which are necessary
to get it to work with mac80211.
It would be a great if mac80211 would do to the encryption and
decryption asynchronously. As this would work for other ciphers
and also allows crypto offload to dedicated crypto hardware.
Does it actually hurt some existing code or functionality?
It definitely helps with wifi software crypt.
Thanks,
Ben
