This patch introduces a mdev (mediated device) based hardware vhost backend. This backend is an abstraction of the various hardware vhost accelerators (potentially any device that uses virtio ring can be used as a vhost accelerator). Some generic mdev parent ops are provided for accelerator drivers to support generating mdev instances. What's this =========== The idea is that we can setup a

Hi all: There are hardwares 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
