Hm, well. Actually, it should serve as nothing more than a code example
that does nothing useful except shows how to use it. Just like the packet
fanout example in the same file. It should just provide a starting point
for people to grab it and build something bigger out of it.

In a follow-up patch I could add a test case, /specificly designed/ to
do basic sanity checks. I think if people are looking for that, they
might not be starting under tools/testing/selftests/net, no?
