Date: Sat, 13 Mar 2010 19:11:17 +0800 From: Herbert Xu <herbert@...dor.apana.org.au> To: "David S. Miller" <davem@...emloft.net>, netdev@...r.kernel.org Subject: ipv6: Send netlink notification when DAD fails Hi: 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.
