When I compiled/installed -current, and started setting things up again, I
noticed that gif devices now expect IPv6 prefix lengths of 128.  Most
providers use 127, and some even use 64 as prefix lengths for tunnels.  I
was just curious why the change was made to only support prefix lengths of
128.  Is there an RFC that covers this perhaps?
