That's a very good point indeed!  I didn't think of the possibility of
supporting SLAAC over raw-ip interfaces. I only did manual address
config on IPv6 too. Thanks for verifying that the modem replies to RS
over raw-ip.

I'll see if I can figure out what it takes to automatically assign a
link local address for these interfaces. I guess that should be done in
any case for proper IPv6 support
