[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
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

[PATCH 6/9] virtio: provide a method to get the IRQ affinity mask for a virtqueue
This basically passed up the pci_irq_get_affinity information through
virtio through an optional get_vq_affinity method. It is only implemented
by the PCI backend for now, and only when we use per-virtqueue IRQs.

[PATCH 5/9] virtio: allow drivers to request IRQ affinity when creating VQs
Add a struct irq_affinity pointer to the find_vqs methods, which if set
is used to tell the PCI layer to create the MSI-X vectors for our I/O
virtqueues with the proper affinity from the start. Compared to after
the fact affinity hints this gives us an instantly working setup and
allows to allocate the irq descritors node-local and avoid interconnect
traffic. Last but not least this will allow

[PATCH 2/6] virtio: add context flag to find vqs
Allows maintaining extra context per vq. For ease of use, passing in

[Patch net] vsock: improve tap delivery accuracy
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.
