I am interested in performance(throughput) of the application when we change the batching factor at NIC and in application. I can change the batch size in the DPDK application, but I am not sure how to do at the NIC. What needs to be changed in the code to change the batch size at NIC and what is the default batch size at NIC in DPDK ? Thanks, Ankit Bhardwaj
