[lwip-devel] tcp_output does not force seg sent out

[narke]

Hi,

I found it's not always that the tcp_output() call can make a segment
to be sent out.   Sometimes it still accumulated data until TCP_MSS
reached before output a segment.  In what situation that tcp_output()
does not output segment? And, how do I ensure the output behavior
really happen?

* note:  I believe the send and receive window size are large enough.


Thanks in advance.
