You can use ethtool to do this:: - sudo ethtool -L <interface> combined 1 + sudo ethtool -L <interface> combined 1 If you want to only see part of the traffic, you can program the NIC through ethtool to filter out your traffic to a single queue id that you can bind your XDP socket to. Here is one example in which UDP traffic to and from port 4242 are sent to queue 2:: - sudo ethtool -N <interface> rx-flow-hash udp4 fn - sudo ethtool -N <interface> flow-type udp4 src-port 4242 dst-port \ - 4242 action 2 + sudo ethtool -N <interface> rx-flow-hash udp4 fn + sudo ethtool -N <interface> flow-type udp4 src-port 4242 dst-port \ + 4242 action 2 A number of other ways are possible all up to the capabilitites of the NIC you have. |
