Re: [dpdk-dev] Queries on Pktgen

Hi Keith,

Thanks for your response.
I did try giving the pcap file in the -s option but I was not able to see
any pcap files getting generated by the pktgen.
I also tried giving in the -f option but it also doesnt seem to recognize.
Please let me know how to resolve this.

Regards
Shankari.V
