From 1b34be74cbf18f5d58cc85c7c4afcd9f7d74accd Mon Sep 17 00:00:00 2001 From: YOSHIFUJI Hideaki Date: Sat, 28 Jun 2008 14:18:38 +0900 Subject: ipv6 addrconf: add accept_dad sysctl to control DAD operation. - If 0, disable DAD. - If 1, perform DAD (default). - If >1, perform DAD and disable IPv6 operation if DAD for MAC-based link-local address has been failed (RFC4862 5.4.5). We do not follow RFC4862 by default.
