gif interface not passing IPv6 packets

[Li, Qing]

I believe there is actually another bug needs fixing. Let me confirm and will provide
another patch later.

Actually saying that. I've found a problem meaning some of my software
is broken now.

Just noticed that lo0 doesn't have a ::1 address:

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
        options=3<RXCSUM,TXCSUM>
        inet 127.0.0.1 netmask 0xff000000

If I try and add one I get this:

root at tao[~]# ifconfig lo0 inet6 ::1 prefixlen 128
ifconfig: ioctl (SIOCAIFADDR): File exists
