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).
