commit 5e868ddd8263d2f7b61a702891252cc2bacb1c07
Author: Andre Detsch <adetsch@br.ibm.com>

Add new TCP and IP functions
This patch adds some basic functions to the IP and TCP tapsets.
Mainly, it's possible to get the iphdr and tcphdr from a sk_buff structure.
As a consequence, a TCP probe called tcp.receive() was created and
is probed every time a TCP packet is received, and a lot of
useful fields is available, as the TCP flags.
Also a small example that works like tcpdump for received TCP packets was
created.
This patch was tested on x86 and ppc machines, on 2.6.18 kernel and also on
mainline one.
