Subject: [PATCH v4 0/4] 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,
so while Jason rework is done, a patch is added to disable
CVQ and features that depend on it (tested also with DPDK
v23.07-rc1).

In this v4, LSM hooks are added to allow/deny application
to create/destroy/open devices based on their type (Net,
Block).

- Add LSM hooks (Michael)
- Rebase

=================
- Use allow list instead of deny list (Michael)

v1 -> v2 changes:
=================
- Add a patch to disable CVQ (Michael)

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

Maxime Coquelin (4):
  vduse: validate block features only with block devices
  vduse: enable Virtio-net device type
  vduse: Temporarily disable control queue features
  vduse: Add LSM hooks to check Virtio device type
