Hi Bruce: Actually I want to use the TESTPMD app as a packet-generator/checker driving the KNI-enabled NICs. Is there an easy way to packet generate/check than testpmd?
Please see attached.

You are using a DPDK process to pull packets from a physical NIC and send them to the kernel using KNI. Then you want to have testpmd pull those packets from the KNI device using pcap back into user- space before returning them via the same sort of path i.e. userspace, pcap to kernel, kni back to userspace and out again. Can you explain why you want such a setup, as it will work very slowly compared to just running everything directly in userspace? As for your specific issue. If you have a DPDK process running to manage the KNI device, that is the process holding the lock on .rte_config. You will need to run the second process with a different file-prefix parameter to have two DPDK processes running side-by-side. Regards, /Bruce
