## AF_XDP

XDP socket(AF_XDP) is an excellent bypass kernel network framework. The zero
copy feature of xsk (XDP socket) needs to be supported by the driver. The
performance of zero copy is very good. mlx5 and intel ixgbe already support
this feature, This patch set allows virtio-net to support xsk's zerocopy xmit
feature.

You're moving the driver and adding a major feature.
This really needs to go via net or bpf.
If you have dependencies in other trees please wait for
after the merge window.

If so, I can remove the first two commits.

Then, the sq uses the premapped mode by default.
And we can use the api virtqueue_dma_map_single_attrs to replace the
virtqueue_dma_map_page_attrs.

And then I will fix that on the top.

Hi Micheal and Jason, is that ok for you?

I would go with what looks easy for you but I think Jakub wants the
series to go with next-next (this is what we did in the past for
networking specific features that is done in virtio-net). So we need
to tweak the prefix to use net-next instead of vhost.

Thanks

Thanks.
