Yes, it works when the if is down when you don't have the
set_mac_address callback afaik. Having it allows changing when the
interface is up which is useful with nowadays userland thingies that
tend to keep interfaces up to poll their link (argh ! sungem is smart
enough to continue managing the link when the interface is down, but not
all drivers are)
