In newer firmwares with WDA support, you can check that with qmicli

ModemManager already switches the interface mode automatically, so not
applicable to MM. At qmicli level we just try to map the QMI commands,
so I don't think we should be issuing e.g. WDA checks when WDS
connection is requested. The only place I think we could add this
check is in the qmi-network script; although in that case we could
also just request to switch to 802-3 via the CTL command, as
ModemManager does.

Well, that's because it's not a Sierra thing anymore.
