Those "wwan0" and "wwan1" are the "full devices", they're not the NET
ports, as far as I know (may be mistaken though). Do you see any NET
port listed in "ip link"? Does the hwsim driver somehow register a net
port associated to those exposed control ports?

I'll try to play with all that at some point :)
