-Subject: [PATCH] netfilter: nf_flow_table: rework hardware offload timeout
- handling
-
-Some offload implementations send keepalive packets + explicit
-notifications of TCP FIN/RST packets. In this case it is more convenient
-to simply let the driver update flow->timeout handling and use the
-regular flow offload gc step.
-
-For drivers that manage their own lifetime, a separate flag can be set
-to avoid gc timeouts.
