Subject: [PATCH v2] USB: serial: option: add Quectel RM500K module support
Add usb product id of the Quectel RM500K module.
RM500K provides 2 mandatory interfaces to Linux host after enumeration.
- /dev/ttyUSB5: this is a serial interface for control path. User needs
to write AT commands to this device node to query status, set APN,
set PIN code, and enable/disable the data connection to 5G network.
- ethX: this is the data path provided as a RNDIS devices. After the
data connection has been established, Linux host can access 5G data
network via this interface.
"RNDIS": RNDIS + ADB + AT (/dev/ttyUSB5) + MODEM COMs
