[lwip-users] Enabling ACK_DELAY

Hi,
 
I'm in the process of porting an existing application to a new platform that uses lwIP.  This application operates in real time using a series of commands from a server.  The application layer of this client always responds to the server application with an ACK, NAK  or some form of data. To reduce overhead, the stack in the original product used the application response to return the network ACK. In lwIP though, I see a network ACK followed immediately by an application response.   Is there any way to remove the network ACK?  I've noticed there is a constant TF_ACK_DELAY but it does not seem to have any impact on these ACKs.  I have turned off Nagle so not to conflict with TF_ACK_DELAY.  Thanks
 
Steve
