Date: Wed, 07 Dec 2011 15:23:45 +0800 From: Li Wei <lw@...fujitsu.com> To: netdev <netdev@...r.kernel.org> CC: "David S. Miller" <davem@...emloft.net>, yoshfuji@...ux-ipv6.org Subject: [PATCH] ipv6: Fix for adding multicast route for loopback device automatically. There is no obvious reason to add a default multicast route for loopback devices, otherwise there would be a route entry whose dst.error set to -ENETUNREACH that would blocking all multicast packets.
