What version of the Tulip driver is being used here? I have the version from
Donald Becker (v0.10) straight off of his ftp site plus the one line mod to
avoid the incorrect reassignment of ether_init() (I think that was it, in any
case you just have to comment out the #include <etherdevice.h> line in the
tulip driver to make it work). In my system this driver has been rock solid
including two full incoming news feeds and three outgoing full news feeds on
the ethernet. I pass enough packets each day that I get in the range of 3 to 4
times as many ethernet interrupts as I do timer interrupts, with scsi
interrupts falling a close third to the timer interrupts.
