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.
