Public bug reported: * Explain the feature Assured connections are those connections which deemed of "higher quality" and less like to expire than non-assured connections, as they passed some stricter rule (e.g in udp reply + connection lasting more than 2 seconds). This feature offloads only those connections. * How to test Create OVS bridge with 2 devices mlx5 rep devices. Enable HW offload and configure regular connection tracking OpenFlow rules: e.g: ovs-ofctl del-flows br-ovs ovs-ofctl add-flow br-ovs arp,actions=normal ovs-ofctl add-flow br-ovs "table=0, ip,ct_state=-trk actions=ct(table=1)" ovs-ofctl add-flow br-ovs "table=1, ip,ct_state=+trk+new actions=ct(commit),normal" ovs-ofctl add-flow br-ovs "table=1, ip,ct_state=+trk+est, actions=normal" Run a short UDP connection (< 2 seconds), e.g: on mlx5 VF1 iperf -s -u on mlx5 VF2 iperf -c <ip> -t 1 -u
Run longer UDP connection (> 2 seconds), e.g: on mlx5 VF1 iperf -s -u on mlx5 VF2 iperf -c <ip> -t 10 -u With the above commit quick lived UDP connections (< 2 seconds) will not be offloaded to the flow table as can be checked by cat /proc/net/nf_conntrack | grep -i offload while connections lasting more than 2 seconds (and of course double sided) will be offloaded. * What it could break.
