Add the member sw_backup to the structures switchdev_obj_ring_role_mrp and switchdev_obj_in_role_mrp. In this way the SW can call the driver in 2 ways, once when sw_backup is set to false, meaning that the driver should implement this completely in HW. And if that is not supported the SW will call again but with sw_backup set to true, meaning that the HW should help or allow the SW to run the protocol. For example when role is MRM, if the HW can't detect when it stops receiving MRP Test frames but it can trap these frames to CPU, then it needs to return -EOPNOTSUPP when sw_backup is false and return 0 when sw_backup is true.
