Hello all,
I had a "working" install of pktgen that would transfer data but not
provide statistics. The setup are two Netronome NICs connected
together. It was suggested there was a problem with the Netronome PMD,
so I reinstalled both the Netronome BSP and DPDK. Now I'm getting the
following error with trying to start up pktgen with: ./pktgen -c 0x1f
-n 1 -- -m [1:2].0

I tried unbinding the nics and rebinding. I read in an older mailling
post that setup.sh needs to be run every reboot. I executed it, and it
looks like a list of things to install pktgen that I had done manually
again after the most recent reboot. The output of the status check
script is below:
./dpdk-devbind.py --status

Does anyone have any suggestions?
