configure network card as gigabit full duplex

I'm having a D-Link DL2000-based Gigabit Ethernet network card, but I'm not able to run it on a gigabit port. (I'm using SuSE 9.1.)

Trying mii-tool -v I receive:
  eth0: negotiated 100baseTx-FD, link ok
  product info: vendor 00:50:43, model 5 rev 4
  basic mode:   autonegotiation enabled
  basic status: autonegotiation complete, link ok
  capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control
  link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
I want to configure it as gigabit full duplex, but just don't know how to do it (beginner...). What command would I have to try to make the network card working on a gigabit port?

Thanks in advance!

Run the following command:

	ethtool eth0
This should give you detailed information about your connection. Then have a look at:

	man ethtool
and it's tell you how to try to force the connnection. But it might be that the other machine is not allowing your gigabyte ethernet card to operate at full speed.

I tried the command
ethtool -s eth0 speed 1000
, but ethtool eth0 tells me the following (before and after using ethtool -s...):

Settings for eth0:
Supported ports: [ 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: MII
Transceiver: internal
Auto-negotiation: on
Link detected: yes

Did I use the wrong command?
I know definitely thet card and port are able to do gigabit. Could it be that one of it is broken?
