[lwip-devel] Help with UDP Iperf server

[antonio]

Hi all,

I am developing a small UDP Iperf server. I am able to connect to it and get
measurements. 
However,  I am unable to detect, when the  client intends to end the
connection. I need it because, I intend to supply 
-d option at the client side, which enables bidirectional measurement.

>From the example in apps/ there is a structure 
lwiperf_settings_t; which states /** This is the Iperf settings struct sent
from the client */
I print the field flags and are always zero.

All hints are welcome.
