Hi Andrew:

it makes no sense when auto-negotiation is not supported.
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.


Thanks!
