Display seq/ack #s.
Seems the current approach is bad. We need enumerators :(
Enumerator/Iteratee seems to work perfectly good.
Process IP level using Enumerators.
TCP processing.
Cleanup.
Style fixes.
Transform error into empty Chunk (pt. 1)
s/error/putStrLn (pt. 2)
Use Maybe to signal errors (and silently remove the erroneous packets).
Make non-fatal errors for TCP too.
Process TCP conversations (based on port numbers).
Final steps in TCP layer.
Fix small problem with succ maxBound.
Display length of payload in debugging.
Use relative SeqNos.
TODOs.
Switch (temporarily) to a capture to check TCP packet flow.
