The full title is:
Intel 8255x 10/100 Mbps Ethernet Controller Family
Open Source Software Developer Manual
The manual is intended to support the maintenance of the e100 driver (or the
best driver for the PRO/100 networking hardware ;-). The manual covers the
82557, 82558, 82559, 82550, and 82551 Ethernet controllers.
I would like to thank Jeff Garzik for encouraging this publication, and for
having the patience to deal with the Intel machine.
I would also like to thank the Intel editors and reviewers: Carolyn
Abrigana, Larry Bates, Julie Donnelly, John Ronciak, Wen-Hwa Tao, Eli
Kupermann, David Valdez, Colleen Culbertson, and especially Glenn Begis for
not giving up.
