dec21140 drivers from the i386/pc386 and powerpc/mcp750 (all Motorola

This TULIP driver can be used on BSPs that support PCI bus.
It can handle any DEC21140 based Ethernet controller.
It works on big or little endian target.
It has been tested with powerpc/mcp750 BSP (OnBoard Ethernet
controller) and i386/pc386 BSP (D-Link DFE-500TX Ethernet board).
