I have two iperf clients sending UDP packets to a iperf server. Once the
test is completed, the Server side results for only one of the streams
is reported both on the client and server.
Iperf client:
# iperf -c 10.0.50.100 -B 10.0.50.1 -u -b1G -t100 &
# iperf -c 10.0.50.100 -B 10.0.50.2 -u -b1G -t100 &

I'm not sure why the results for [4] aren't reported by the server. Can
someone help?
