Remove the AF_XDP samples from samples/bpf as they are dependent on
the AF_XDP support in libbpf. This support has now been removed in the
1.0 release, so these samples cannot be compiled anymore. Please start
to use libxdp instead. It is backwards compatible with the AF_XDP
support that was offered in libbpf. New samples can be found in the
various xdp-project repositories connected to libxdp and by googling.

Will you (or Maciej) be submitting these samples to XDP-tools[1] which
is the current home for libxdp or maybe BPF-examples[2] ?
[1] https://github.com/xdp-project/xdp-tools
[2] https://github.com/xdp-project/bpf-examples
I know Toke is ready to take over maintaining these, but we will
appreciate someone to open a PR with this code...

The code in samples/bpf/xsk_fwd.c is interesting, because it contains a
buffer memory manager, something I've seen people struggle with getting
right and performant (at the same time).
You can get my ACK if someone commits to port this to [1] or [2], or a
3rd place that have someone what will maintain this in the future.
