FYI, I stumbled across this thread documenting how to enable the NCM
function(s):
https://forum.sierrawireless.com/t/hl7692-linux-networking-activation/12371/2

Somebody still has to implement that as a plugin though... But I guess
it might be worth it if if works for NCM on other XMM7160 modems too?  I
don't remember if we ever got that flying?  The EM7345 I have does not
have a usable NCM config at all.

OK.... Googling a bit more brought me to this old discussion of an
Infineon plugin:
https://www.mail-archive.com/modemmanager-devel@lists.freedesktop.org/msg02985.html

That didn't lead anywhere, did it?  But the code is still there:
https://github.com/freedesktop/ModemManager/tree/paul/infineon/plugins/infineon
Maybe recycle it and see if it works for Sven and the HL7692?

Going with MBIM is definitely easier ;-)
