From 724876deab47f7d73ad9772464ff754bfe452846 Mon Sep 17 00:00:00 2001 From: Sebastian Hesselbarth Date: Tue, 24 Jun 2014 12:18:09 +0200 Subject: net: orion: generate unique port device names Marvell Orion ethernet IP originally is multi-port capable, but SoCs using the IP usually have multiple single-port controllers built in. Currently, orion-gbe driver registers each port device with a constant name, which causes a name conflict with multiple controller instances. This patch uniquifies port device name generation by prepending controller's base register address to resolve the name conflict.
