Emil,
When I set that, this is what I get:
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 1000baseT/Full
10000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: 10000baseT/Full
Advertised pause frame use: Symmetric
Advertised auto-negotiation: Yes
Speed: Unknown!
Duplex: Unknown! (255)
Port: Twisted Pair
PHYAD: 0
Transceiver: external
Auto-negotiation: on
MDI-X: Unknown
Supports Wake-on: umbg
Wake-on: g
Current message level: 0x00000007 (7)
drv probe link
Link detected: no
So I am still relying on auto-negotiation which isn't working between the
switch and the NIC (at least that is my understanding). Is there no way to
specify the speed using the standard ethtool commands?
