Hi, I'm currently developing a driver for a hardware crypto offload engine that is capable of offloading both ESP and AH in IPSec. I've noticed that none of the crypto drivers in 2.6.28 do offload for ahash and that the netkey AH implementation both use synchronous hashes. Are the synchronous software versions likely to be more efficient than hardware offloading or is there an architectural reason for not using async hashes?
