Well, it's not microcontroller specific at all, and not cheap, but the ultimate TCP/IP book is TCP/IP Illustrated, by W. Richard Stevens. If you want a TCP/IP "ultimate reference manual". ISBN: 0201633469 Probably not what you're looking for, but thought I'd mention it if you really want to see the nitty-gritty of TCP/IP stacks. There's also a newer book out about TCP/IP Implementation in the same series, but I don't have that one. TCP/IP Illustrated is pulled down off the shelf as a reference regularly, though...
