From c9607c932585e6757ad1c378751030c2a4234227 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 24 Feb 2017 10:12:41 +0100 Subject: [PATCH] net: mvpp2: Handle eth device naming in multi-CP case correctly Currently, the naming of the ethernet ports is not handled correctly in the multi-CP (Communication Processor) case. On Armada 8k, the slave-CP also instantiates an ethernet controller with the same device ID's. This patch now takes this into account and adds the required base-id so that the slave-CP ethernet devices will be named "mvpp2-3 ...". This patch also updates my Copyright notice to include 2017 as well.
