title: iperf3 results in packets per second?
body: <p>Can <code>iperf3</code> report measurements also in terms of packets per second, when generating UDP traffic?</p>
  
  <p>A typical output with the verbose mode is the following:</p>
  
  <pre><code>Test Complete. Summary Results:

  iperf Done.

  <p>I see that in <code>iperf2</code> one could specify the input rate in <code>pps</code>, but there is no mentioning of the measured received rate (I don't see this feature in <code>iperf3</code> anyway)</p>
