Hi Alfredo, Thanks for your quick response. I have another question instead of distributing the packets like round robin basis, if we want to distribute packets to the threads based on the tuple information; do we need to set " pfring_set_cluster(thread[id]->pd, 55, cluster_per_flow" ?.
Also how to verify if the packets are distributed based on cluster_per_flow?
