Hi Monika,
"D" is a really bad state; it indicates that the network stack or the
network card had to drop network packets. It's like "O", but worse.
so, how what does
benchmark_rate --rx_rate 1e6
say?
What is your network card, what is your OS, are you using a firewall,
and are you sure everything involved is 1Gbit Ethernet capable (USRPs
cannot work with 100Mbit/s Ethernet, because it doesn't support the
frame format).
Best regards,
Marcus
