Trying to confirm how latency was being calculated before with the UDP_RR test. Looking at its raw output, I see that transactions per second is probably used to calculate RTT, with interim results like:

```
NETPERF_INTERIM_RESULT[0]=3033.41
NETPERF_UNITS[0]=Trans/s
NETPERF_INTERVAL[0]=0.200
NETPERF_ENDING[0]=1511296777.475
```

So RTT = (1 / 3033.41) ~= 330us

And this likely takes the mean value of all transactions and summarizes it at the end of the interval, then the calculated latency was what was plotted in flent?
