The main purpose of this patch is to offload ECDSA computations to virtio-crypto dev. We can modify the backend of virtio-crypto to allow hardware like Intel QAT cards to perform the actual calculations, and user-space applications such as HTTPS server can access those backend in a unified way(eg, keyctl_pk_xx syscall).
