I know you really like shash, but I think there are some clear
benefits to be had by coupling this with ahash.

If we do this properly, we should be able to immediately use the
mb code with IPsec.  In the network stack, we already aggregate
the data prior to IPsec with GSO.  So at the boundary between
IPsec and the Crypto API, it's dividing chunks of data up to 64K
into 1500-byte packets and feeding them to crypto one at a time.

It really should be sending the whole chain of packets to us as
a unit.

Once we have a proper mb interface, we can fix that and immediately
get the benefit of mb hashing.

Cheers,
