Hi, I am not very familiar with the github project you listed. But IIUC, the vdev param should be ‘--vdev=net_pcap0,iface=eno1’ and eno1 should be the Intel 100G E810 NIC port.

Thank you so much for replying. 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?

Vdev param is for virtual devices and you are using real hardware devices. So you don't need to consider this if you only want to start up the E810 NIC.
