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.
