The
code name of the
DEC 10/100 ethernet chip, the DS2114x.
Donald Becker at
Cesdis uses these things almost exclusively in their
Beowulf clusters.
Update: Intel purchased the DEC semiconductor line, so now Tulip chips are being made by Intel. Lite-On also makes a clone, and PNIC and NetGear relabel them. Also, Donald Becker is no longer working at NASA, and so is hosting all his Linux device drivers at his Scyld.com site.
