-          Enable caching of tunnel headers and the output path.  This can lead
-          to a significant performance increase without changing behavior.  In
-          general it should not be necessary to adjust this setting.  However,
-          the caching can bypass certain components of the IP stack (such as
-          <code>iptables</code>) and it may be useful to disable it if these
-          features are required or as a debugging measure.  Default is enabled,
-          set to <code>false</code> to disable.
