Latest working kernel version: 2.6.23.9
Earliest failing kernel version: 2.6.21
err, according to this, we had the bug in 2.6.21 and then fixed it in 2.6.23.9, so this is a report of an already fixed bug ;)
Can you please clarify the version numbers here?

Distribution:
Hardware Environment: e1000 with 82571 chip
Software Environment: CentOS 4.5
Problem Description:
We have a machine with the e1000(82571) driver which could not detect the correct link mode with a switch supports 1000 Mbps/s. I just find that the ethtool can't support 10 Mbps/s Half and 1000 Mbps/s Full mode. Therefore, the e1000 code should be fixed by add all modes at the 216 lines ine1000_ethtool.c. It is as follow:
hw->autoneg_advertised|=ecmd->advertising|ADVERTISED_TP | ADVERTISED_Autoneg;Steps to reproduce:
1. Add a entry ' ETHTOOL_OPTS="autoneg on" ' in the/etc/sysconfig/network-scripts/ifcfg-eth0;
2. Run '/etc/init.d/networkrestart';
3. Run 'ethtool eth0', it displays the speed is 100 Mbps/s. But the real link mode should be 1000 Mbps/s

a bit moot because 82571 support is moving to e1000e and thus I will (probably) not fix this bug. all 82571 support will be removed from e1000 from 2.6.26 onwards.
Please re-test against e1000e from 2.6.25-rc5 - if the bug is still in that driver then we need to look at it again. Either that or reproduce against an 8254x adapter?
