+From 0cd0ed7b0b966704236e07fc1d3bd099deb407a7 Mon Sep 17 00:00:00 2001
+From: John Daley <johndale@cisco.com>
+Date: Tue, 31 Jan 2017 12:59:23 -0800
+Subject: [PATCH] The mac_addr_add callback function was simply replacing the
+ primary MAC address instead of adding new ones and the mac_addr_remove
+ callback would only remove the primary MAC form the adapter. Fix the
+ functions to add or remove new address. Allow up to 64 MAC addresses per
+ port.
