tcpad status report #2
So, I found some time to continue my SoC work. tcpad is now capable of handling the most important TCP FSM transitions, like CLOSE_WAIT, FIN_WAIT_1, SYN_SENT, etc. I also implemented a basic timer facility that cleans up old connections in TIME_WAIT state. This still doesn’t honor the 2MSL required by the RFC, but it’s a start. 
I also cleaned the code a little and improved the debugging macro.
Next is SEQ/ACK analysis.
