From a02e4b7dae455151c423e2f69ef222c502a321fd Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 12 Dec 2010 21:39:02 -0800 Subject: ipv6: Demark default hoplimit as zero. This is for consistency with ipv4. Using "-1" makes no sense. It was made this way a long time ago merely to be consistent with how the ipv6 socket hoplimit "default" is stored.
