Sierra Wireless EM7345 and IPv6

[Bjørn Mork]

I just got myself one of these things, curious as I am...  Received it
todat and I've already run into trouble :-) Connecting works fine, but
the modem doesn't report the assigned prefix for some reason.  Just an
LL address and gateway:

ModemManager[17046]: <debug> [1401208713.950188] [mm-bearer-mbim.c:212] ip_configuration_query_ready(): IPv4 configuration available: 'none'

ModemManager[17046]: <debug> [1401208713.951481] [mm-port.c:93] mm_port_set_connected(): (wwan1): port now connected

And I cannot see any response to any Router Solicit or DHCPv6 solicit
either, making it pretty hard to actually use this connection for
something.  Any hints?
