====================
bridge: mrp: Fix br_mrp_port_switchdev_set_state

Based on the discussion here[1], there was a problem with the function
br_mrp_port_switchdev_set_state. The problem was that it was called
both with BR_STATE* and BR_MRP_PORT_STATE* types. This patch series
fixes this issue and removes SWITCHDEV_ATTR_ID_MRP_PORT_STAT because
is not used anymore.
