We get a lot of questions about locking particular flows in the kernel, and I'm afraid this description might give the impression that this will be the actual time it's kept in the kernel. (The name of the variable indicates that that's not the case, but I think most people will miss that.) What about adding a sentence like the following to the end? "Note that ovs-vswitchd may expire flows more quickly than the configured value based on system load and other factors." --Justin _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
