How does this work? You identify user-defined flows and apply ATR on the rest of the flows? >> To enable it, add "hw.ixgbe.cooperative_atr=1" on /boot/loader.conf >> >> Usage is as follows: >> ixgbetool <ifname> [operation] >> add_sig_filter <proto> <src_ip> <src_port> <dst_ip> <dst_port> >> <que_index> >> show_sig_filter >> del_sig_filter <id> I believe, I can somehow test whether the signature filter works or not by generating custom traffic, creating matching filter, directing the traffic to a specific queue and watch that queue. But how do I test/see ATR (application targeted receive) in action? Traffic for a specific application should follow the application on different cpus, right? Any guidance on how to do that would be great. cheers, Hiren <skip>
