[lwip-devel] Help with UDP Iperf server |

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.
