Can't use gif in -current

[John Klos <john%ziaspace.com@localhost>]

Hi,

Does anyone know what's changed which might've broken gif in -current? 
After switching from NetBSD-4 to current, I get this:

ifconfig gif0 inet6 2610:1f8::1:10:d86 2610:1f8::1:10:d85 prefixlen 128
ifconfig: SIOCAIFADDR_IN6: Invalid argument

My /etc/ifconfig.gif0 looks like this:

create
tunnel 192.80.49.1 209.212.68.38
inet6 2610:1f8::1:10:d86 2610:1f8::1:10:d85 prefixlen 128

But it configures to this:

gif0: flags=8050<POINTOPOINT,RUNNING,MULTICAST> mtu 1280
        tunnel inet 192.80.49.1 --> 209.212.68.38

...and now all of my IPv6 is gone... Any ideas?
