Yesterday I installed pfstat 2.2 on FreeBSD RELENG_6. It compiled cleanly,
but fetching the statistics failed with "ioctl DIOCIGETIFACES not supported
by device" (not the exact wording).

To get it running I used:
<http://www.fabiankeil.de/sourcecode/freebsd/pfstat-2.2.diff>
(update for sysutils/pfstat from 1.7 to 2.2)

Could someone with FreeBSD PF foo please check patch-pf.c
for correctness?
