+From 16df7dc5901c1cb2a40f6adbd0d9423768ed8210 Mon Sep 17 00:00:00 2001
+From: Tim Harvey <tharvey@gateworks.com>
+Date: Thu, 15 May 2014 00:29:18 -0700
+Subject: [PATCH] net: igb: add phy read/write functions that accept phy addr
+
+Add igb_write_reg_gs40g/igb_read_reg_gs40g that can be passed a phy address.
+The existing igb_write_phy_reg_gs40g/igb_read_phy_reg_gs40g become wrappers
+to this function.
