Hi All,
I followed the flow listed here
https://kb.ettus.com/Getting_Started_with_DPDK_and_UHD with UHD 3.15
and DPDK 17.11, but I am unable to run uhd_usrp_probe, it fails. At
the end of the email the result of uhd_usrp_probe is attached.
Running Ubuntu 18.04. Installed UHD from source and installed dpdk
from apt-get.
The app note worked mostly as expected except for the sudo
dpdk-devbind --bind=vfio=pci 02:00.0 commands. However, this failed as
it failed to bind to the device. I had to run sudo dpdk-devbind
--bind=vfio-pci enp2s0f0 instead, and that worked.
Any suggestions on what to try next?
Thanks
Colby

I haven't run DPDK in my lab so, I'm guessing here.
It's complaining that there's no IP address associated with the
interface, which will almost certainly cause downstream problems.
