To integrate MRP into the bridge, first the bridge needs to be aware of ports that are part of an MRP ring and which rings are on the bridge. Therefore extend bridge interface with the following: - add new flag(BR_MPP_AWARE) to the net bridge ports, this bit will be set when the port is added to an MRP instance. In this way it knows if the frame was received on MRP ring port - add a list of MRP instances Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> --- include/linux/if_bridge.h | 1 + net/bridge/br_private.h | 4 ++++ 2 files changed, 5 insertions(+)
