* AF_XDP documentation
In kernel [[https://www.kernel.org/doc/html/latest/networking/af_xdp.html][documentation for AF_XDP]].
XDP-tools also contain documentation in [[https://github.com/xdp-project/xdp-tools/blob/master/lib/libxdp/README.org#using-af_xdp-sockets][libxdp for AF_XDP]], explaining
how to use the API, and the difference between the control-path and
data-path APIs.
When developing your AF_XDP application, we recommend familiarising
yourself with the core AF_XDP concepts, by reading the kernel
[[https://www.kernel.org/doc/html/latest/networking/af_xdp.html][documentation for AF_XDP]]. And XDP-tools also contain documentation in
[[https://github.com/xdp-project/xdp-tools/blob/master/lib/libxdp/README.org#using-af_xdp-sockets][libxdp for AF_XDP]], explaining how to use the API, and the difference
between the control-path and data-path APIs.

ring-queues* which are all Single-Producer Single-Consumer (SPSC)
ring-queues. A set of these four queues are needed *for each queue*
on the network device (netdev).
