Can you tell me which netstat command you have in mind? I tried “netstat -Q”, it shows a few drops but not that much that it would explain the CARP drops. What I can tell you is, that especially CARP on the corresponding server is just sending out packets as long as it is the master box and CPU0 load is below 100%. It doesn’t receive any CARP traffic at all, just normal network traffic. What I see is, that those CARP packets are not sent anymore if CPU0 has 100% load -> if that happens the server switches to standby and the traffic is gone on the machine. So because of this behavior we would like to have an option, which allows us to have Control Plane Traffic (LACP, CARP,…?) in RSS RX queue 0 and nothing else. Question is, what would Control Plane traffic be. Hopefully as well CARP/VRRP,… We tried hw.cxgbe.cong_drops=1, but it doesn’t help in our case. Can you explain a bit what your patch will do? Am I right that you will post the link later on here? Cheers Josef
