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

Virtio-net driver control queue implementation is not safe when used with VDUSE. If the VDUSE application does not reply to control queue messages, it currently ends up hanging the kernel thread sending this command. Some work is on-going to make the control queue implementation robust with VDUSE. Until it is completed, let's disable control virtqueue and features that depend on it.

Hi all: The code used to busy poll for cvq command which turns out to have several side effects: 1) infinite poll for buggy devices 2) bad interaction with scheduler So this series tries to use sleep instead of busy polling. In this version, I take a step back: the hardening part is not implemented and leave for future investigation. We use to aggree to use interruptible sleep but it
