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

From: Cong Wang <cong.wang at bytedance.com> When virtqueue_add_sgs() fails, the skb is put back to send queue, we should not deliver the copy to tap device in this case. So we need to move virtio_transport_deliver_tap_pkt() down after all possible failures.
