ipf -I -6 -Fa clears both v4 and v6 lists. I and /etc/rc.d/ipfilter reload expect it to only clear v6 lists. I happen not to have a v6 list installed, but that does not seem to matter. How-To-Repeat: load an ipfilter v4 list from /etc/ipf.conf, run /etc/rc.d/ipfilter reload, notice that the active v4 list is empty.

This is by design. As of IP Filter 5, IPv4 and IPv6 rules are stored in the sane table internally.
If it is by design, /etc/rc.d/ipfilter on 10.1-REL needs updating
Fix MFCed.
