Michael, thanks very much for taking the time to help debug this.

I have done some more experimentation and have discoved that Tulip clones 
vary widely in how much reset time they require.

The LNE100TX and MX98715 seem to require an eternity after a 

   outl(0, ioaddr + CSR0); /* reset the card */

before they are able to transmit again.

LC82C168 cards on the other hand seem to require no time at all. Since 
the reset section of the tulip code is common between cards, we have a 
problem. I suppose I could conditionalize the wait-after-reset time, but 
perhaps a slightly longer value will avoid the extra code complexity.

Would you (and anyone else using tulip/clone cards) be so kind as to 
download ntulip-0.75b7 from http://www.thinguin.org/ and try that version 
of ntulip.c on your card?  There should be a slight (3 sec) delay on 
startup, but it should be much shorter than the TFTP timeout after the 
first packet time-out.  The Linux kernel BOOTP request delay should be 
the same.

Thanks and Regards,

Marty
