I presumed that you used ethtool, but if you made changes to the code post the diff, so that we can review it. > We are trying to follow the description in the Intel's > PCI/PCI-X Family of Gigabit Ethernet Controllers Software Developers > Manual > 82540EP/EM, 82541xx, 82544GC/EI, 82545GM/EM, 82546GB/EB, and 82547xx > Rev. 3.9 > > --------------------- > In there it says: > > 11.6.2 Forced Operation: > Forced operation can be used to establish 10 and 100 links, and 1000 > links for test purposes.

A little bit above this section there is also a text that says: "Auto-Negotiation is the only method allowed by the 802.3ab standard for establishing a 1000BASE-T link, although forced operation could be used for test purposes." this is what I was refering to when I mentioned that GB/full only works with autoneg. I didn't realize that you were trying to use the master/slave mode. How did you do this? Again post diff if you changed the code. Otherwise I believe the version of e1000 you are using does not support it by default (despite what the README claims, setting E1000_MASTER_SLAVE will have no effect). A bit more information about what you're trying to solve might help as well.
