then up of the bonded interface.

+Subject: [PATCH 1/2] net/enic: fix setting MAC address when a port is
+ restarted
+
+enic_disable() removed the MAC address when a port was shut down but
+enic_enable() didn't add the MAC address back when the port was
+started again. Move where we set the MAC address for the adapter from
+enic_setup_finish() to a enic_enable() so that port restarting works
+properly.

+Subject: [PATCH 2/2] net/enic: fix removing old MAC address when setting new
+ one
+
+enic_set_mac_address() meant to remove the old MAC address before
+setting the new one, but accidentally tried removing the new MAC
+address before setting the new MAC address.
