So I don't know why I can't change the speed / duplex of the NIC using mii-tool.
From man mii-tool :
SIOCGMIIPHY on 'eth?' failed: Operation not supported
The interface in question does not support MII queries. Most
likely, it does not have MII transceivers, at all.
Just for reference, ethtool eth0 output for my Atheros AR8151 chip (disconnected), which does support mii queries :
Code:
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Speed: Unknown!
Duplex: Unknown! (255)
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
MDI-X: Unknown

Wake-on: g
Current message level: 0x0000003f (63)
drv probe link timer ifdown ifup

So there are some differences than yours, although not sure if they matter.
Basically, I'm stumped too..
