For me the following did not work: ethtool -i eth3 driver: i40e ... ethtool eth3 Settings for eth3: Supported ports: [ ] Supported link modes: 40000baseCR4/Full 40000baseSR4/Full 40000baseLR4/Full Supported pause frame use: Symmetric Supports auto-negotiation: No Advertised link modes: 40000baseCR4/Full 40000baseSR4/Full 40000baseLR4/Full Advertised pause frame use: No Advertised auto-negotiation: No Speed: Unknown! Duplex: Unknown! (255) ethtool -s eth3 speed 10000 Cannot set new settings: Operation not supported not setting speed lspci shows it as; 06:00.1 Ethernet controller: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ (rev 01) Regards, Kevin ------------------------------------------------------------------------------ Transform Data into Opportunity.
