I should handle it differently with the case supports auto-negotiation and not supports auto-negotiation. I will fix it in next version, result like below: Settings for eth0: Supported ports: [ FIBRE ] Supported link modes: 25000baseCR/Full 25000baseSR/Full 1000baseX/Full 10000baseCR/Full 10000baseSR/Full 10000baseLR/Full Supported pause frame use: Symmetric Supports auto-negotiation: No Supported FEC modes: None BaseR Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Advertised FEC modes: Not reported Speed: 10000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: internal Auto-negotiation: off Current message level: 0x00000036 (54) probe link ifdown ifup Link detected: yes Wish I have understood your comments correctly.
