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 ?"
