Re: [dpdk-dev] KNI sample application running procedure

As par error message, it seems error lies in validation. But it seems right
Can you try to run the app without kthread option. if you haven't tried
that. just to pin point the problem.

./kni -c 0x0f -n 2 -- -P -p 0x3 --config="(0,2,3),(1,0,1)"
while executing, load kni module with single mode option.
