layerscape: add support for fixed-link on RGMII interfaces This is required on the Traverse LS1043 boards to support SFP and xDSL plug-ins. This will not be needed on kernel 4.14. Signed-off-by: Mathew McBride <matt@traverse.com.au>

From f27ef8941ca29b2d10428754be51e8ee06bb1263 Mon Sep 17 00:00:00 2001
From: Mathew McBride <matt@traverse.com.au>
Date: Mon, 7 Aug 2017 10:19:48 +1000
Subject: [PATCH] Recognize when an RGMII Link is set as fixed (in the device
tree) and set up the MAC accordingly

layerscape: add Traverse LS1043-S support The Traverse LS1043-S board is a router board based on NXP/Freescale's LS1043 SoC, with 4x1GBase-T, 1 SFP and 1 SFP+, as well as miniPCIe and M.2 LTE. Unlike the Layerscape reference boards, the LS1043-S board has NAND flash and uses the mainline U-Boot. This patch implements support for the LS1043-S board, as well as the earlier LS1043-V board. It is our intention that all boards in this family (LS1043-S and later, Five64) will boot the same binary. Not included in this patchset are the hwmon drivers not in the kernel (emc1704,pac1934) or the bootloader. Signed-off-by: Mathew McBride <matt@traverse.com.au>
