Subject: [PATCH] net: usb: cdc_ether: add u-blox 0x1313 composition.
|
||
|
|
|
||
|
|
Add CDC-ECM support for LARA-R6 01B.
|
||
|
|
|
||
|
|
The new LARA-R6 product variant identified by the "01B" string can be
|
||
|
|
configured (by AT interface) in three different USB modes:
|
||
|
|
* Default mode (Vendor ID: 0x1546 Product ID: 0x1311) with 4 serial
|
||
|
|
interfaces
|
||
|
|
* RmNet mode (Vendor ID: 0x1546 Product ID: 0x1312) with 4 serial
|
||
|
|
interfaces and 1 RmNet virtual network interface
|
||
|
|
* CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1313) with 4 serial
|
||
|
|
interface and 1 CDC-ECM virtual network interface
|
||
|
|
The first 4 interfaces of all the 3 configurations (default, RmNet, ECM)
|
||
|
|
are the same.
|
||
|
|
|
||
|
|
In CDC-ECM mode LARA-R6 01B exposes the following interfaces:
|
||
|
|
If 0: Diagnostic
|
||
|
|
If 1: AT parser
|
||
|
|
If 2: AT parser
|
||
|
|
If 3: AT parset/alternative functions
|
||
|
|
If 4: CDC-ECM interface
