You're right, so we can write:
@kick_vq_with_data: Kick the virtqueue and supply extra data
(only if VIRTIO_F_NOTIFICATION_DATA is
negotiated)
@vdev: vdpa device
@data for split virtqueue:
16 bits vqn and 16 bits next available index.
@data for packed virtqueue:
16 bits vqn, 15 least significant bits of
next available index and 1 bit next_wrap.
