MBIM devices usually do not support DHCP as they are raw IP interfaces,
not really ethernet. After running mbim-network and getting a
successful connect response, you run:
. /tmp/mbim-network-state-cdc-wdm0
mbim-cli -d /dev/cdc-wdm0 --query-ip-configuration=${TRID}
and then parse and apply that configuration to the network interface,
update DNS/resolv.conf, and update default route if required. mbim-
network doesn't currently do this for you, because DNS and routing are
system-wide properties that must be set in cooperation with other
tools, and mbim-network is just a simple demo-type utility.
