This bit indicates that the conntrack entry is offloaded to hardware flow table. nf_conntrack entry will be tagged with [HW_OFFLOAD] if it's offload to hardware. cat /proc/net/nf_conntrack ipv4 2 tcp 6 \ src=1.1.1.17 dst=1.1.1.16 sport=56394 dport=5001 \ src=1.1.1.16 dst=1.1.1.17 sport=5001 dport=56394 [HW_OFFLOAD] \ mark=0 zone=0 use=3 Note that HW_OFFLOAD/OFFLOAD/ASSURED are mutually exclusive. Changelog: * V1->V2: - Remove check of lastused from stats. It was meant for cases such as removing driver module while traffic still running. Better to handle such cases from garbage collector.
