this doesn't do what you think it does. You think it matches
everything but 8.8.8.8 and 8.8.4.4, while in reality, it matches
everything. Feed that rule through
pfctl -nvf -
and you'll see it expanded to
match log on vic0 proto icmp from any to ! 8.8.8.8
match log on vic0 proto icmp from any to ! 8.8.4,4
the list negation discussion is as old as pf.
