A simple and inexpensive integrated way for connecting a variety of standard computer devices, including networking integrated circuit devices, to other standard and customized integrated circuit devices, is provided as follows. An integrated circuit device has an interface, the interface is capable of transferring data from a MAC layer to a PHY layer, and also is capable of transferring data from the PHY layer to the MAC layer. There is a pin on the integrated circuit device for setting the interface in a first mode or a second mode, and when the interface is in the first mode the interface is capable of transferring signals between a MAC device and a PHY device, and when the interface is in the second mode the interface is capable of transferring signals between a first MAC device and a second MAC device. Also, there is a set of I/O lines for connecting a standard integrated circuit device having a MAC device to the inventive integrated circuit device operating in the second mode, the interface transferring signals between the MAC device in the standard integrated circuit and a second MAC device in the inventive integrated circuit.
