I wasn't able to turn it off in my first trial because when autoneg is not working I also have to set the duplex mode. So the following four things worked: ethtool -s end1 autoneg off duplex full speed 1000 master-slave forced-slave ethtool -s end1 autoneg off duplex full speed 1000 master-slave forced-master ethtool -s end1 autoneg off duplex full speed 100 master-slave forced-slave ethtool -s end1 autoneg off duplex full speed 100 master-slave forced-master So for our use case everything is working fine now and we can live with the fact that autoneg is the default. Tested with a mv88q2110 device. Tested-by: Stefan Eichenberger <eichest@xxxxxxxxx> Thanks, Stefan
