Subject: [Hipsec] Renaming the HMAC HIP Parameter

We called it HMAC and HMAC_2 as all we allowed was HMAC as the keyed 
Message Authentication Code.

But now there is CMAC and GMAC.

So what should I use in the ID replace HMAC?

MAC
or
kMAC

???

Then we will have to negotiate the MAC along with the HIP-TRANSFORM and 
which will be a MUST implement?  I can see arguements for any of them as 
the MUST with the others as MAY.

GMAC could give coding savings when used with GCM.
HMAC gives interoperablity with older stuff.

Votes and hums please?
