+Creates a vhost-user cryptodev backend, backed by a chardev @var{chardevid}.
+The @var{id} parameter is a unique ID that will be used to reference this
+cryptodev backend from the @option{virtio-crypto} device.
+The chardev should be a unix domain socket backed one. The vhost-user uses
+a specifically defined protocol to pass vhost ioctl replacement messages
+to an application on the other end of the socket.
+The @var{queues} parameter is optional, which specify the queue number
+of cryptodev backend for multiqueue vhost-user, the default of @var{queues} is 1.
