Is the LLP for the wwan set as 802.3?

i.e. did you explicity run:
$ qmicli -d /dev/cdc-wdm0 --wda-set-data-format="802-3"

You can check that with:
$ qmicli -d /dev/cdc-wdm0 --wda-get-data-format

If the interface is not in 802.3 mode, dhclient doesn't know yet how to manage the raw-ip network interface.
