[pox-dev] Create TCP packet

[Murphy McCauley]

The .win attribute of the TCP class should be an integer, and it's just put into the 16-bit window field verbatim.  IIRC, in the absence of window scaling, this is just the number of bytes (beyond whatever is being ACKed) that you're willing to receive.  (If you're just trying to get a client to think a connection is open, I think you can probably just set it to 1 -- 0 may not be a good idea.)

I'd check the RFC or a good TCP reference for additional information.  Or just try it. :)
