From 90bbb74af68b3255bc298731f8b60d5668877306 Mon Sep 17 00:00:00 2001 From: Yan Burman Date: Thu, 7 Feb 2013 02:25:24 +0000 Subject: [PATCH] net/mlx4_en: Save previous MAC address of the port so we can replace it later In preparation to having more than one unicast MAC per port, we need to keep track of the previous MAC address in the flow of ndo_set_mac_address, so that mlx4_en_replace_mac will know what to replace.
