From 99e904c1f036145946a8439e3f3c5180139640a6 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Wed, 4 Nov 2015 12:25:52 +0530 Subject: armv8: lsch3: Fix lane protocol parsing logic Current implementation only consider SGMIIs for dpmac initialization. XFI serdes protocols also uses dpmac. Also, fix lane protocol parsing logic to consider both XFIs and SGMIIs.
