Have a look at the book written by Richard Stevens "The Implementation 
(TCP/IP Illustrated, Volume 2)" here is a link:
http://www.amazon.com/exec/obidos/tg/detail/-/020163354X/ref=sib_rdr_dp/104-9931268-0446302?%5Fencoding=UTF8&no=283155&me=ATVPDKIKX0DER&st=books
I haven't read the book, so I don't know if it has what you're asking, but 
I know the book describes BSD TCP/IP implementation in details
