From 08cc83cc7fd8e6c3670ff545ef2bbfbc01a02d87 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 8 Jul 2019 23:31:13 -0400 Subject: net: dsa: add support for BRIDGE_MROUTER attribute This patch adds support for enabling or disabling the flooding of unknown multicast traffic on the CPU ports, depending on the value of the switchdev SWITCHDEV_ATTR_ID_BRIDGE_MROUTER attribute. The current behavior is kept unchanged but a user can now prevent the CPU conduit to be flooded with a lot of unregistered traffic that the network stack needs to filter in software with e.g.: echo 0 > /sys/class/net/br0/multicast_router Signed-off-by: Vivien Didelot Signed-off-by: David S.
