Subject: [PATCH v1 0/2] vduse: add support for networking devices

This small series enables virtio-net device type in VDUSE.
With it, basic operation have been tested, both with
virtio-vdpa and vhost-vdpa using DPDK Vhost library series
adding VDUSE support using split rings layout (merged in
DPDK v23.07-rc1).

Control queue support (and so multiqueue) has also been
tested, but requires a Kernel series from Jason Wang
relaxing control queue polling [1] to function reliably.

RFC -> v1 changes:
==================
- Fail device init if it does not support VERSION_1 (Jason)

Maxime Coquelin (2):
  vduse: validate block features only with block devices
  vduse: enable Virtio-net device type
