Because there are two kind of crypto device, one is virtio-crypto which is
a virtual crypto device (And virtio-crypto device is a real crypto device seen by the guest). 
The other is cryptodev backend device.  I have no good idea to name the kind
of virtio-crypto device, so named to legacy crypto device refer to Net stuff.

Do you have any suggestion? Thanks!
