It would have been even nicer if they documented it so we wouldn't havt to guess... You wouldn't happen to have a windows *.inf file for this device as well? Would be interesting to see how ZTE intended these functions to be matched. Anyway, I think we should replace the device specific entry in the option driver with 3 vendor+class matches for the 3 serial functions. The qmi_wwan entry worked by luck because it matches on the interface number. But we might consider replacing that entry as well if ZTE are going to use ff/06/00 for the QMI/wwan function on more of these devices. I'll keep my eyes open.
