freebsd/share/examples/pf/queue2
Max Laier 9d7ccc0ffa Bring in some examples (and create space for future work here):
- Add OpenBSD example rulesets as advertised in etc/pf.conf and pf.conf(5)
- Tweak the pointer to fit the FreeBSD default location share/examples/pf
- Account for the new directory in BSD.usr.dist (no hier(7) change required
  as share/examples is an opaque item there).
