Change ndo_set_mac_address to dev_set_mac_address because dev_set_mac_address provides a way to notify network layer about MAC change. In other case, services may not aware about MAC change and keep using old one which set from network adapter driver.
As example, DHCP client from systemd do not update MAC address without notification from net subsystem which leads to the problem with acquiring the right address from DHCP server.
