Subject: [PATCH net 2/3] net: mvneta: enable change MAC address when interface is up

From: Dmitri Epshtein <dima@...vell.com>

Function eth_prepare_mac_addr_change() is called as part of MAC
address change. This function check if interface is running.
To enable change MAC address when interface is running:
IFF_LIVE_ADDR_CHANGE flag must be set to dev->priv_flags field
