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).
Related works are also described in following patch series:
