Hi,

so no, iperf is not compiled for Xenomai. In order to do real-time
networking with Xenomai, you need:
- a network driver for Xenomai, likely using RTnet
- an application compiled to use Xenomai services, if you want to port
an application using the POSIX API, which is probably the case of iperf,
you may have a look at this guide:
