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. Refer to the netdev thread entitled "Linux IPv6 DAD not full conform to RFC 4862 ?" http://www.spinics.net/lists/netdev/msg52027.html Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
