[xdp-cloud] seed code for xdp-cloud repo

[David Ahern]

Jesper,

I recall you had thoughts about initial seed code - something other than
just pulling what I have in my bpf-progs repo - e.g., the l2fwd code.
Anything I can do to help get this kickstarted?

David

My concerns with your repo[1] is primarily how you integrate libbpf.
E.g. I don't like having libbpf.a directly part of the repo.

Toke and I have created a repo for bpf-examples[2], that we believe
have a better integration (and auto-detection) for libbpf.  I will
prefer we can create a similar build environment in our xdp-cloud[3]
git repo.  The repo[3] already exist, but without any code.

If you have time, you can look at bpf-examples[2] and see what you
think, and maybe even go ahead and create the build env if you like our
approach.

Note, I do plan to make some changes[4] to bpf-examples around
splitting the include files into two directories, to make it more clear
what comes from kernel and what belong to project itself.

Ease of use for a personal repo that moves across nodes, and I did not
want libbpf as a submodule. I also had changes to libbpf that just made
it easier to install a copy into the repo for rapid development.
