This TULIP driver can be used on BSPs that support PCI bus.

It can handle any DEC21140 and DEC21143 based Ethernet controller
although the DEC21143 support has only been tested on Intel.
  
It works on big or little endian target.

The DEC21140 has been tested with powerpc/mcp750 BSP (OnBoard Ethernet
controller) and i386/pc386 BSP (D-Link DFE-500TX Ethernet board).

The DEC21143 has been tested only on the i386/pc386 using
the Kingston KNE100TX with 21143PD chip.
