Lost in space for a long time, but it finally came back to us from
some ancient code tombs. This patch adds a minimal runnable example
of Linux' packet mmap(2) from Chetan Loke's TPACKET_V3. Special
thanks to David S. Miller, and also Eric Leblond and Victor Julien!

tools/testing/selftests/net  seems a better place to get another
program ?

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?
