  We couldn't specify the rule for filtering tunnel traffic since an
  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
          pass ipv6 from any to any
  But, now, you can specify it like:
          pass ip4 from any to any proto ipv6
