Message-ID: <4F548D59.1060600@cn.fujitsu.com> Date: Mon, 05 Mar 2012 17:54:33 +0800 From: Li Wei <lw@...fujitsu.com> To: "David S. Miller" <davem@...emloft.net> CC: netdev <netdev@...r.kernel.org> Subject: [PATCH] IPv6: Fix not join all-router mcast group when forwarding set. When forwarding was set and a new net device is register, we need add this device to the all-router mcast group.
