libexec/ftp-proxy - ftp proxy for pf sbin/pfctl - equivalent to sbin/ipf sbin/pflogd - deamon logging packets via if_pflog in pcap format usr.sbin/authpf - authentification shell to modify pf rulesets Bring along some altq headers used to satisfy pfctl/authpf compile. This helps to keep the diff down and will make it easy to have a altq-patchset use the full powers of pf. Also make sure that the pf headers are installed. This does not link anything to the build. There will be a NO_PF switch for make.conf once pf userland is linked. Approved by: bms(mentor)
