   4 Subject: [PATCH] net: usb: cdc_ether: add u-blox 0x1313 composition.
   5
   6 Add CDC-ECM support for LARA-R6 01B.
   7
   8 The new LARA-R6 product variant identified by the "01B" string can be
   9 configured (by AT interface) in three different USB modes:
  10 * Default mode (Vendor ID: 0x1546 Product ID: 0x1311) with 4 serial
  11 interfaces
  12 * RmNet mode (Vendor ID: 0x1546 Product ID: 0x1312) with 4 serial
  13 interfaces and 1 RmNet virtual network interface
  14 * CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1313) with 4 serial
  15 interface and 1 CDC-ECM virtual network interface
  16 The first 4 interfaces of all the 3 configurations (default, RmNet, ECM)
  17 are the same.
  18
  19 In CDC-ECM mode LARA-R6 01B exposes the following interfaces:
  20 If 0: Diagnostic
  21 If 1: AT parser
  22 If 2: AT parser
  23 If 3: AT parset/alternative functions
  24 If 4: CDC-ECM interface
