From 1d39a5e4ce09172358a5435a3411a46e76a04bb4 Mon Sep 17 00:00:00 2001 From: Janne Huttunen Date: Thu, 13 Aug 2015 16:21:46 +0300 Subject: STAGING: Octeon: Use common helpers for determining interface and port Currently the Octeon Ethernet driver hardcodes the mapping between interface/port and IPD port number. Since we have generic helpers for the very same purpose, we might as well use them instead. This prevents having the same information in multiple places.
