[Bhavesh Davda] Thanks for catching that. I was wondering why nobody responded.

I leave it up to you and the wider DPDK community to decide if this example is useful. It was useful to us (VMware) and a couple of partner companies in reproducing a packet drop on transmit issue at a telco/NFV operator lab more easily than setting up the DPDK-based VNF from the vendor along with a hardware load generator to generate the application-specific packet load. It was much easier to just run this example application in a VM to reproduce the packet drop issue.

What is different? I didn't find any other simple apps that only mimic Tx bursty behavior similar to this application. Maybe I missed some example application that has such a capability.
