Thanks for quick reply. 

Adding delay between polls will be a good idea, worry is that it may introduce additional latency for latency sensitive applications. Any suggestion on the open source tool that can be used to generate high pkt rate?

 Are you sure that the packet rate isn't such that only two packets are received between polls of the interface?

Try putting a small delay between the polls, or increase the packet rate.

Hello Experts,
While testing App using vmxnet3 interface, it is not receiving more than two or one pkt in packet rx burst.
I am using rte_port_ethdev_reader_rx() with packet burst size as 32 packets, i am sending traffic using "iperf tool" from VM interface connected to VDS in Esxi. App running inside VM connected to VMXNET3 interface is not receiving more than 2 pkts in each rx burst. 

Any suggestions why rte_port_ethdev_reader_rx() is not getting more than 2 pkts with vmxnet3 interface?
Appreciate your help.
