So this doesn't work. Could you try with decimation 10 (or 12, until
you get only a few underruns)?
Interestingly, the 2MB/sec test fails although the faster speeds are ok.
We've noticed that too. Note that the 32 MB/s speed is really 16 MB/s
in each direction.
It would be cool if benchmark_usrp.py tried decimation 14, 12, and 10
also, rather than stopping at 16 (and interpolation values with those
rates).
