netdev experts, When there is a L2 switch underneath the network interface a flooding of multicast at the bridge interface results in one copy of this going through each of the slave resulting in multiple multicast packets reaching the underlying switch. L2 switch also duplicates the multicast packet on each egress port as done in software bridge. This is undesirable as it reduces the available bandwidth to half when multicast packets are involved.
Is there something that can be done to avoid software bridge flooding mulicast through a ip command or similar or to be done in the network driver? I have a TODO item to add dsa support in our netcp driver. If this is already solved by dsa, I can handle it as part of this work.
