pf(4) testing needed

[Theo de Raadt <deraadt@cvs.openbsd.org>]

So our packet filter development process is starting to lock before the
3.3 release.

Both 3.1 and 3.2 shipped with minor annoying bugs in the pf code, for
things which not everyone uses, but someone did.

It would be really nice if the most serious pf users out there would
download -current snapshots, install them, and try to use the regular
and obscure new features.  If you find bugs now, we can fix the before
3.3 ships.  If you find them once 3.3 is running, you'll be annoyed.

So help us out, ok?
