net/fec: carrier off initially to avoid root mount failure
with hardware slow in negotiation, the system did freeze while trying to mount root on nfs at boot time. the link state has not been initialised so network stack tried to start transmission right away. this caused instant retries, as the driver solely stated business upon link down, rendering the system unusable. notify carrier off initially to prevent transmission until phylib will report link up.
