Beginner's information on 2.6 implementation of networking

[Chase Douglas <cndougla@xxxxxxxxxx>]

I have an idea for linux networking at the level of manipulation of how sk_buffs
are used. However, I do not know where in the linux kernel code to begin looking
for where sk_buffs are manipulated. I was wondering if there were any good
resources on the 2.6 implementation of the tcp/ip protocol. I have found a few
documents on 2.2 and 2.4, but many of the functions listed do not seem to be
present in the 2.6 kernel. Even if I could have a list of function calls from
send to receive using the tcp/ip protocol, it would help a lot.

Thank you
