netfilter: flowtable: add nf_flowtable_time_stamp
This patch adds nf_flowtable_time_stamp and updates the existing code to use it. This patch is also implicitly fixing up hardware statistic fetching via nf_flow_offload_stats() where casting to u32 is missing. Use nf_flow_timeout_delta() to fix this. Fixes: c29f74e0df7a ("netfilter: nf_flow_table: hardware offload support") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Acked-by: wenxu <wenxu@ucloud.cn>
