I think I'm having exactly this problem on my own network. I have a
mixture of cards that the tulip driver supports (Macronix, 21140, etc.)
and I get different transfer rates depending on who is sending and who
The main problems occur when I'm sending data to one of the Macronix
cards. They generate a large number of collisions. I believe it is
because they are trying to operate in full-duplex mode, but as far as I
can tell, they have been forced to half-duplex. I load the module with
options tulip options=3 debug=1 max_interrupt_work=40 # 100-base-T
What else can I do to prove that the card is/isn't trying to go
