[v2,10/15] virtio-crypto: set capacity of crypto legacy hardware

Commit Message

Gonglei (Arei) Sept. 13, 2016, 3:52 a.m. UTC

Set the crypto legacy hardware's capacity according to the
backend peer cryptodev's capacity. We only support only one
queue at present.

Virtio crypto device is a kind of crypto legacy hardware.
