I guess to. But for some HW devices eth_mac_addr() is needed (when they
does not support "life" mac change")

I was thinking about this. Maybe probably __eth_mac_addr() which does
not have netif_running() check and eth_mac_addr() calling
netif_running() check and __eth_mac_addr() after that.

What do you think?
