That way e.g. batman-adv should continue to be compile and useable without having to have a kernel compiled with bridge code in the future. This is what the first patch is supposed to do. The second patch adds a third multicast export for the bridge which e.g. batman-adv is supposed to use, too, soon: Just like the bridge disables its multicast snooping activities if no querier is present, batman-adv needs to do the same if bridges are involved. These three exports should be the final ones needed to marry the bridge multicast snooping with the batman-adv multicast optimizations recently added for the 3.15 kernel, allowing to use these optimzations in common setups having a bridge on top of e.g. bat0, too. So far these bridged setups would fall back to simple flooding through the batman-adv mesh network for any multicast packet entering bat0. More information about the batman-adv multicast optimizations currently implemented can be found here: http://www.open-mesh.org/projects/batman-adv/wiki/Basic-multicast-optimizations The integration on the batman-adv side could afterwards look like this, for instance (now including the third export): http://git.open-mesh.org/batman-adv.git/commitdiff/61e4f6af4b7a21ed4040f2e711d50c778e5b6d93?hp=6ae4281474675fbca5bedcf768972a32db586eb6 Cheers, Linus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
