------------------

From: Dmitri Epshtein <dima@marvell.com>

commit 928b6519afeb2a5e2dc61154380b545ed66c476a upstream.

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
