Re-enable using ethtool when at full duplex. Can it be the case that this is just a follow-up error? In one of the mails from yesterday I showed you my patch to disable 1000 MB/s ... and still I had the link-always-down. Similarly when I used a 10/100 MB/s switch only. Both scenarios disabled 1000 MB/s, one more strictly than the other :-)
