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 UDP connection, e.g: on mlx5 VF1 iperf -s -u on mlx5 VF2 iperf -c <ip> -u -t 10 Optional: In different terminal, while traffic is running, check for offload: tcpdump -nnepi <RELEVANT_MLX5_REP> udp and see no iperf udp packets. Dump conntrack with relevant ip: cat /proc/net/nf_conntrack | grep -i <ip> See tuples were offloaded: ipv4 2 udp 17 src=1.1.1.2 dst=1.1.1.3 sport=56394 dport=5001 packets=2 bytes=112 src=1.1.1.3 dst=1.1.1.2 sport=5001 dport=56394 packets=1777 bytes=665340 [HW_OFFLOAD] mark=0 zone=0 use=3 Flush the tuples: conntrack -F Verify tuples are deleted: cat /proc/net/nf_conntrack | grep -i <ip> Before fix, the above tuple shows again, after fix, it's deleted, and shows nothing. * What it could break. Conntrack -F / -D not working on offloaded tuples.
