[ Upstream commit eea8ce81fbb544e3caad1a1c876ba1af467b3d3c ]
This modem has 7 interfaces, 5 of them are serial interfaces and are driven by cdc_acm, while 2 of them are wwan interfaces and are driven by cdc_ether: If 0: Abstract (modem) If 1: Abstract (modem) If 2: Abstract (modem) If 3: Abstract (modem) If 4: Abstract (modem) If 5: Ethernet Networking If 6: Ethernet Networking
Without this change, the 2 network interfaces will be named to usb0 and usb1, our QA think the names are confusing and filed a bug on it.
After applying this change, the name will be wwan0 and wwan1, and they could work well with modem manager.
