Merge documentation to mainline kernel

[eloydegen]

The documentation about AF_XDP on kernel.org seems also to be focused on end users instead of kernel developers, shouldn't it be better to merge the documentation in this repository into the mainline kernel?

It was the plan to merge the documentation in this repo into the kernel, but I've dropped that plan.
... maybe I should just delete the documentation in this repo.

You only seem to have found the AF_XDP kernel.org doc.

The BPF doc in kernel dir is here: https://www.kernel.org/doc/html/latest/bpf/index.html

And the most successful (and maintained) ref guide is: https://cilium.readthedocs.io/en/latest/bpf/

Seems reasonable, I think the issue can be closed then :)

The issue is a good reminder that I need to clean up this doc mess ...
... Thus, keep it open to force me to work on this ;-)
