+ <para>The Tunnel Encapsulation Limit option specifies how many additional
+ levels of encapsulation are permitted to be prepended to the packet.
+ For example, a Tunnel Encapsulation Limit option containing a limit
+ value of zero means that a packet carrying that option may not enter
+ another tunnel before exiting the current tunnel.
+ (see <ulink url="https://tools.ietf.org/html/rfc2473#section-4.1.1"> RFC 2473</ulink>).
+ The valid range is 0-255 and <literal>none</literal>. Defaults to 4.
