From 1b0fce8c8e69485e49a7d34aac3d4c2a2aa15d62 Mon Sep 17 00:00:00 2001 From: Davide Tronchin Date: Thu, 29 Jun 2023 12:37:36 +0200 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 Signed-off-by: Davide Tronchin Reviewed-by: Simon Horman Signed-off-by: David S.
