Fully agree with you that we need a sample, but a better location for
it is in libxdp as xdpsock demonstrates how to use libxdp interfaces.
We cannot require that people install libxdp just to be able to
compile samples/bpf/. And the sample should be simpler IMO. So let us
use this as an opportunity to improve things.
