+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.
