Using the latest 'rfnoc-devel' (eec24d7b) with my N310, I get the following
error when running the example program 'benchmark_rate'. The error message
indicates no PPS detected whenever the channel count is greater than one.
Note that this is not a new error (it was present prior to me updating
today). I am wondering if someone from Ettus can confirm this error using
the simple command line below?
