The HW is notified in following cases: SWITCHDEV_OBJ_ID_MRP: This is used when a MRP instance is added/removed from the MRP ring. SWITCHDEV_OBJ_ID_RING_ROLE_MRP: This is used when the role of the node changes. The current supported roles are MRM and MRC. SWITCHDEV_OBJ_ID_RING_TEST_MRP: This is used when to start/stop sending MRP_Test frames on the mrp ring ports. This is called only on nodes that have the role MRM. In case this fails then the SW will generate the frames. SWITCHDEV_OBJ_ID_RING_STATE_STATE: This is used when the ring changes it states to open or closed. This is required to notify HW because the MRP_Test frame contains the field MRP_InState which contains this information. SWITCHDEV_ATTR_ID_MRP_PORT_STATE: This is used when the port's state is changed. It can be in blocking/forwarding mode. SWITCHDEV_ATTR_ID_MRP_PORT_ROLE: This is used when port's role changes. The roles of the port can be primary/secondary. This is required to notify HW because the MRP_Test frame contains the field MRP_PortRole that contains this information.
