IPv6 support was committed:
- Stop treating `ip' and `ipv6' as special in `proto' option as they
conflict with /etc/protocols.
- Disuse `ipv4' in `proto' option as it is corresponding to `ipv6'.
- When protocol is specified as numeric, treat it as it is even it is
41 (ipv6).
- Allow zero for protocol as it is valid number of `ip'.
Still, we cannot specify an IPv6 over an IPv4 tunnel like before such
as:
pass ipv6 from any to any
But, now, you can specify it like:
pass ip4 from any to any proto ipv6
