there's lot of optimization space for this.

[RFC PATCH 0/4] mdev based hardware virtio offloading support
Hi all:
There are hardware that can do virtio datapath offloading while having
its own control path. This path tries to implement a mdev based
unified API to support using kernel virtio driver to drive those
devices. This is done by introducing a new mdev transport for virtio
(virtio_mdev) and register itself as a new kind of mdev driver. Then
it provides a unified way for kernel virtio driver to talk with mdev
device implementation.
Though the series only contain kernel driver support, the goal is to
make the transport generic enough to support userspace drivers. This
means vhost-...
