This message is from the driver and it means that the interface lost link for some reason.

To force speed/duplex you need to use "autoneg off", but as John pointed out this will be invalid configuration if your link partner is set to auto. To reset the autonegotiation use ethtool -r instead. > which I assume simply restarts autonegotiation.

It's not obvious and I have not seen the link go down unless the cable was disconnected, or perhaps a problem with the link partner of some sort.
