i have a 21041 dec tulip which has failed to work with
linux-2.4.5-pre[3-5] kernel drivers. (it also fails with the
sourceforge devel version tulip-1.1.7)

it appears that the card gets lodged in full duplex mode. however,
this could just be a superficial syndrome.

anyhow, here is the output of tulip-diag -mm -aa -f from the *broken*
driver
