1 | This TULIP driver can be used on BSPs that support PCI bus. |
---|
2 | |
---|
3 | It can handle any DEC21140 and DEC21143 based Ethernet controller |
---|
4 | although the DEC21143 support has only been tested on Intel. |
---|
5 | |
---|
6 | It works on big or little endian target. |
---|
7 | |
---|
8 | The DEC21140 has been tested with powerpc/mcp750 BSP (OnBoard Ethernet |
---|
9 | controller) and i386/pc386 BSP (D-Link DFE-500TX Ethernet board). |
---|
10 | |
---|
11 | The DEC21143 has been tested only on the i386/pc386 using |
---|
12 | the Kingston KNE100TX with 21143PD chip. |
