May be you want to read the question again...I said i am looking for module so i can set tcp flags and ethernet mac address. With Net::RawIP, i can set the MAC address with function ethset. Can you tell which specific function can be used in IO::Socket::INET 6 or other modules (that come up with google search)to achieve that?
Did you follow the link and explore the possibilities that it provided?
If none were helpful, I'm sorry... but your followup would make it easier for others -- more expert in your problem domain than I am -- were you to tell us what you found that's not helpful to you.
