Sorry for the late feedback.
In my experience the kernel docs have rather poor documents for netfilter sysctl
parameters. I often find myself reading the source code for a deeper
understanding of what is going on.
The docs included in this patch are too short in my opinion, example:
+nf_flowtable_tcp_pickup - INTEGER (seconds)
+ default 120
+
+ TCP connection timeout after being aged from nf flow table offload.
Here, having an example of the sequence of events going on with the conntrack
entry and how this sysctl key affects it would be great. Some explanation of the
behavior that may be observed when tuning this value would be nice as well.
Given the patch was merged already, you can feel free to ignore this anyway :-)
