Actually I want to read the packets as per given in this link " https://github.com/ntop/nDPI/tree/dev/example". You can scroll down and see the command "./build/ndpiReader -c 1 --vdev=net_pcap0,iface=eno1 -- -v 1". Here they use --vdev=net_pcap0. I want to read the packets on my port of NIC. I know the above command uses dpdk parameters. So should I not put --vdev or how the above command is supposed to be written?
