Run this to get the sysfs path of the wwan0 interface of the modem:
$ realpath /sys/class/net/wwan0/device
/sys/devices/pci0000:00/0000:00:14.0/usb2/2-3/2-3:2.0

The sysfs path of the full USB modem (what you need to configure in
the netifd config) is the parent directory of the previous sysfs path:
/sys/devices/pci0000:00/0000:00:14.0/usb2/2-3
