From aa7907407adf1358ee39be0e98beaf4c129a78d6 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Fri, 15 Jan 2010 22:13:58 -0800 Subject: [PATCH] USB: gadget: Add DEVTYPE support for Ethernet functions The problem with Ethernet based networking devices is to clearly identify what's their usage. Special interfaces like bridges, WiFi, Bluetooth, WiMAX or WWAN are already using DEVTYPE identification. This patch marks the Ethernet functions of gadgets from the device type "gadget". Automatic setup of these interfaces can now happen from userspace without the need of hardcoding the network interface name.
