A tool to dump / restore pf state table

by alwe for The NetBSD Project

Pf is quite a famous stateful firewall in BSD world, first written for OpenBSD, and then integrated into NetBSD, FreeBSD. For a lots of people, it has replaced the usage of ipf. However, some features are still not available in pf. During this project, we want to provide a replacement for pf to the ipfs(8) tool, a tool which permit to get the state table of the firewall, and restore back, for example, after a reboot.
