Looking forward to that.  Please post as much details as you can about
the modem and testing. I guess it will take some time before this modem
is generally available, based on the MC/EM7455 experiences.

Adding a new ID to qmi_wwan should be no problem if you are able to
build GobiNet.  It's also possible to test the modem by adding the ID
dynamically, using the new_id attribute.  But then you have to take
special care to make sure only the QMI interface(s) are bound to the
qmi_wwan driver.

If you can do any testing in MBIM mode, then those results would also be
interesting.  This should just work without any driver or userspace
changes.  In theory...
