from IPv6 support point of view, PF is much better than IPFilter.
IPFilter passses around pointer to the head of the packet, without
passing around length, therefore is more vulnerable to programming
mistakes (it might have been okay when IPFilter was IPv4-only, but
with IPv6 you have different header length for each packet).
PF always pass around struct mbuf *, therefore length is always
passed around. also, with PF internal structures are protocol-
independent (well, only for IPv4/v6) so it is easier to provide
the same set of functionalities to IPv4 and IPv6.
