It looks the the second volume that goes with "Operating System Design".
I can't be 100% certain, as I didn't find a table of content for either of the 1st edition books, but the 2nd edition of "Operating System Design" includes a section in implementing ethernet, so perhaps the two volumes got combined into one for the second edition.
Operating System Design, Vol. 2: Internetworking with Xinu, ISBN-13: 978-0136374145 (https://www.amazon.com/Operating-System-Design-Vol-Internetw...).
Unfortunately, this book was written in 1987, so it's a bit dated (e.g. no IPv6). I think it's still useful to learn the basics of a TCP/IP implementation.
