n/a
>Environment:
System: FreeBSD server.vk2pj.dyndns.org 7.0-STABLE FreeBSD 7.0-STABLE #18: Sun May 18 15:02:39 EST 2008 root at server.vk2pj.dyndns.org:/var/obj/k7/usr/src/sys/server i386

>Description:
	In its current form on FreeBSD, pf(4) has no mechanism to report
	state changes to the user.  This significantly increases the
	difficulty in debugging pf(4) issues.

>How-To-Repeat:
	Documented deficiency in FreeBSD (see pfsync(4) manpage)

>Fix:
	Port tcpdump's print-pfsync.c, as well as any other required
	infrastructure (eg libpcap patches) from OpenBSD.
