ipv6: Send netlink notification when DAD fails 



If we are managing IPv6 addresses using DHCP, it would be nice
for user-space to be notified if an address configured through
DHCP fails DAD.  Otherwise user-space would have to poll to see
whether DAD succeeds.

This patch uses the existing notification mechanism and simply
hooks it into the DAD failure code path.
