FreeBSD's pf is broken for IPv6.  Its lack of fragment support means a
FreeBSD breaks EDNS0 and other large-packet protocols that rely on
fragment headers.

This was fixed recently as far as I understand.

Have a look at

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=179392

and

https://svnweb.freebsd.org/changeset/base/274709

I think you're confused about the issue I described. I'm talking about pf not supporting fragment headers and as such dropping fragmented packets instead of statefully passing them.
