From 0909e11758bd28848aeb6646e021ec1e031a3f0f Mon Sep 17 00:00:00 2001 From: Herbert Xu <herbert@gondor.apana.org.au> Date: Sat, 27 Feb 2010 19:41:49 +0000 Subject: bridge: Add multicast_router sysfs entries This patch allows the user to forcibly enable/disable ports as having multicast routers attached. A port with a multicast router will receive all multicast traffic. The value 0 disables it completely. The default is 1 which lets the system automatically detect the presence of routers (currently this is limited to picking up queries), and 2 means that the port will always receive all multicast traffic.
