+From 5f62951fba63a9f9cfff564209426bdea5fcc371 Mon Sep 17 00:00:00 2001
+From: Alex Marginean <alexandru.marginean@nxp.com>
+Date: Tue, 27 Aug 2019 15:16:56 +0300
+Subject: [PATCH] drivers: net: phy: aquantia: enable AQR112 and AQR412
+
+Adds support for AQR112 and AQR412 which is mostly based on existing code
+with the addition of code configuring the protocol on system side.
+This allows changing the system side protocol without having to deploy a
+different firmware on the PHY.
