in dom0, how does one get and set the link information for a NIC? In a
non-xen kernel, we could get this info by simply running:
# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: d
Wake-on: d
Link detected: yes
But in a xen kernel (in dom0), a lot of the information is not available.
# ethtool eth0
Settings for eth0:
Link detected: yes
How does one get (and set) this info on dom0?
Thanks for your help.

So eth0 will be a fake dev and your real physical device will probably be peth0 instead. Running ethtool on peth0 should show you all the settings you''d expect.
