I own a tulip based 21041 10base NIC,This is for use with my cable modem 
service. Unfortunately, i need to disable the link beat test to make the 
communication between my cable modem and the nic function.

Donald has said that this is driver version specific. I am working with the 
0.92 driver and the closest match to the above code is:

-------------------------8<--start cut------------------------
/* 21041 transceiver register settings: 10-T, 10-2, AUI, 10-T, 10T-FD*/
static u16 t21041_csr13[] = { 0xEF01, 0xEF09, 0xEF09, 0xEF01, 0xEF09, };
static u16 t21041_csr14[] = { 0xFFFF, 0xF7FD, 0xF7FD, 0x7F3F, 0x7F3D, };
static u16 t21041_csr15[] = { 0x0008, 0x0006, 0x000E, 0x0008, 0x0008, };

static u16 t21142_csr13[] = { 0x0001, 0x0009, 0x0009, 0x0000, 0x0001, };
static u16 t21142_csr14[] = { 0xFFFF, 0x0705, 0x0705, 0x0000, 0x7F3D, };
static u16 t21142_csr15[] = { 0x0008, 0x0006, 0x000E, 0x0008, 0x0008, };

-------------------------8<-----end cut--------------------------

There is no - or + . Should i assume they are positive and so place a "-" 
prefix on the CSR14[] lines to make them opposite? Or just make them 
possitive? Or on all the "t21041_" lines that have CSR13 CSR14 CSR15?
