pf+TSO patch

[Kristof Provost]

A quick update:
Sean Bruno tested the patch and found a problem with rdr rules.
I've managed to reproduce and fix that. The current version on
https://reviews.freebsd.org/D3779 has the fix.

I believe that version to be working correctly (to the point that I
trust it with my own e-mail), but I'd appreciate further testing and/or
review.

Regards,
Kristof
