Hi all,
I have done with netfilter to add 4 bytes to tcp header option. I use
wireshark to check its working, and the result is : for the packets
without data payload I can see 4 bytes in packet correctly; but for the
packets with data payload 4 bytes changing. I'm sure that other fields
of packet (tcp header, ip header) is ok. Any suggestion is appreciated.?

Which is the main reason to add 4 bytes to tcp header via netfilter?
