[lwip-users] TCP transmission issue, with linux server.

[B B]

Hi all,
 
I am using 1.3.0 stable, and I am experiencing a problem, when my unit is communicating with a linux server.
 
I am using the netconn api and using the TCP protocol.
 
So far we have been running test up against a windows server, which have been trouble free.
 
The problem is that the windows server is sending MSS size frames to the unit, but the linux server is splitting the frames.
 
I have tried to enable ip reass. But this didn't help.
 
I have attached the packet capture. The problem is frame no. 10. This is an ack packet with 750 bytes data.
I would have expected it to be a PSH, ACK packet with 1436 bytes of data.
 
Has anyone encountered an simillar issue, or can anyone explain to me, why the linux and windows behave that differently and what a solution might be to this ?
 
best regards,
Martin
