TCP Retransmissions

Ordinarily, you're a terrible place to get code, /prog/, but I must yield.

I'm having trouble with AES encryption increasing on packet retransmissions, so I obviously must detect and discard retransmissions for encryption purposes. Since I'm using WinPcap, I figured that Ethereal would be a good place to go to see how it detects these events. I was wrong.

I can't tell what the shit is going on with such ugly C code. Any of you have an enterprise-level solution to retransmission detection? Thanks for your time.

I'm not sure if its worth explaining if you can't understand what i say.see http://en.wikipedia.org/wiki/Goto

"Used over short distances with well-documented labels, a "goto" can be more
effective, faster, and cleaner than a series of complex flags or other
constructs. The "goto" may also be safer and more intuitive than the
alternative. A "break" is a goto; a "continue" is a "goto" -- these are
statements that move the point of execution explicitly.
