Hello,
I'm trying to configure UHD to work with DPDK and my Intel X550T NIC. When
running the benchmark_rate UHD example, the x310 drops packets and gives
sequence errors even at lower sample rates. Below is an example of the
output from the script. Have I configured something incorrectly?
/usr/local/lib/uhd/examples# ./benchmark_rate --rx_rate 100e6 --args
