        * if.h: Add mtu6 field to struct interface, IPv6 MTU may differ
          from IPv4, and Solaris treats the MTU's differently.
          Add connected_add_by_prefix, for use by later patch.
        * if.c: (connected_add_by_prefix) Add prefix to connected list.
          (if_flag_dump) Solaris: Dump IFF_IPv4/6 flag
          (if_dump) Dump mtu6 flag, for HAVE_IPV6.
