are you using a 'crossover' cable for this? you can't patch two NIC' directly together with a regular patch cable, it has to be a crossover cable that has Tx wired to Rx and visa versa. Also, I've had mixed results using crossover cabling with 1000baseT gig ethernet
A large number of NICs are autosensing. They do not need a crossover cable. I can hook any of my three notebooks together point to point with a regular cable. They figure it out. Many of my switches do not have the MTI/MTO switch; they autosense if they are 'down stream'. I forget which standard. For some reason I am thinking IEEE 802.1ab, but it is probably a different one.
