[dpdk-users] How to use --vdev parameter?

[Utkarsh Kathuria]

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?
Please help

Regards
Utkarsh
