Say, for example, I have a bunch of e1000 adapters in my box and want to dynamically change one's spd/dplx. For that works in the way you described I need to stop all of them and load with autoneg parameter (can I pass this parameter only to single card?) and loose all connection I had on other adapters. It would be better to handle it in ethtool way, since I discovered it's a common behavior. Thanks. AK> hth, AK> Auke -- Best Regards, Alexandr Kotov mailto:a1k@mail.ru
