Oh, note there's a libmbim-devel mailing list for MBIM stuff, I'm cc-

MBIM devices don't have to support DHCP and many don't.  You can use
the static IP configuration reported by mbimcli 1.12.4 and above, which
was just released last week.  That should give you all the info you
need, including address/prefix/gateway/dns/mtu.
