Just to be clear:
* The tests only work with FreeBSD head/master/main.
* The current tests should work with the freebsd, the rack and bbr stack.
However, the tests sometimes need updates to reflect code changes.

I'm happy to have them in the src repo. That way it would be possible
to also support stable/13 and (possibly) stable/12.

No. Just as a note. There do also exist SCTP tests and I had sometime
ago some UDP lite tests. So we might want to have a directory layout
supporting multiple protocols.
