If IPFilter is compiled as a kernel module (ipl), IPv6 rules cannot be

# kldload ipl
# cat /tmp/t
pass out all
# ipf -6 -f /tmp/t
1:ioctl(add/insert rule): No such process

while IPv4 rules (ipf without -6) work perfectly.

If IPFilter is compiled in-kernel (options IPFILTER), then ipf -6 works
as expected.
