...s is not just an idea. I said that has been used on large scale. This is the library for the APP to use the AF_XDP. We has open it. https://gitee.com/anolis/libxudp This is the Alibaba version of the nginx. That has been opened, that supported to work with the libray to use AF_XDP. http://tengine.taobao.org/ I supported this on our kernel release Anolis/Alinux. The work was done about 2 years ago. You know, I pushed the first version to enable AF_XDP on virtio-net about two years ago. I never thought the job would be so difficult. The nic (virtio-net) of AliYun can reach 24,000,000PPS. So I thi...

Currently, vhost-net is the only consumer of vhost infrastructure. So vhost infrastructure and vhost-net driver are in a single module. Separating this as a vhost.ko module and a vhost-net.ko module makes it is easier to share code with other vhost drivers, e.g. vhost-blk.ko, tcm-vhost.ko.
