[PATCH v2 0/3] 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

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
