└─>HL (hoplimit) target support
In linux kernel since version 2.6.14 (release Date: 2005-10-27)  
This option adds a `HL' target, which enables the user to decrement
the hoplimit value of the IPv6 header or set it to a given (lower)
value.

While it is safe to decrement the hoplimit value, this option also
enables functionality to increment and set the hoplimit value of the
IPv6 header to arbitrary values. This is EXTREMELY DANGEROUS since
you can easily create immortal packets that loop forever on the
network.

To compile it as a module, choose M here. If unsure, say N.
