[..]So, I've got confused of the relation with TCP_WND with the sending buffer and queue. I did not find anything relevant in the TCP output functions. Just tcp_connect seems to also be using the value (maybe as a initial parameter for the sending window?)
tcp_connect only uses TCP_WND to initialize snd_wnd to something. This will get updated when receiving the first segment from the remote host (SYN+ACK).
Does that answer all your questions? Simon
