we are using a modified version of that driver with Telit LE922A6 to
support multiple data sessions that, for my understanding, are lacking
in qmi_wwan.

The driver exposes two files:

/sys/testgobi/gobi0
/sys/testgobi/gobi1

writing 1 on that files, make data connection to start, 0 to stop.

Then usb0 and usb0:1 should be configured with the information
returned by the driver.

Daniele
