[PATCH net] net: usb: qmi_wwan: add Quectel RG660QB

From: Sebastian Sjoholm

Date: Thu Sep 03 2026 - 14:03:18 EST


Add support for the Quectel RG660QB 5G module (USB ID 2c7c:013d).
Its QMI interface (interface 4) uses class/subclass/protocol ff/ff/ff
like the other recent Quectel modules, so match it the same way.

The remaining interfaces are handled by the option driver.

Tested with an early sample of the module on a Quectel 5G EVB connected
over USB 3 to a Raspberry Pi 5: qmicli talks to the module via
/dev/cdc-wdm0.
