Just to you and e1000-devel Hi Daniel,
These types of link partner problems do come up. Most times there is nothing that the end-point system can do about it as the actual problem is on the router/switch side of things. The way end-points get around things like this is start the whole link process again which it looks the driver is doing. So other than it taking a short amount of time to re-establish link there are no side effects doing this. That's all that happens correct? If you were able to plug the end-point system into another router/switch port from another manufacturer or back-to-back to another system you probably won't see the problem. Btw, the cheaper the router/switch the more likely you'll run into things like this. It's all about the quality and validation that goes into the HW. If the manufacturer doesn't spend the time and money to do it the customers see issues like this. Hope this helps (at least a little). Sorry we can't be more help for things like this.
