commit b2bdba1cbc84cadb14393d0101a5bfd38d342e0a upstream.
The function br_mrp_port_switchdev_set_state was called both with MRP port state and STP port state, which is an issue because they don't match exactly.
Therefore, update the function to be used only with STP port state and use the id SWITCHDEV_ATTR_ID_PORT_STP_STATE.
The choice of using STP over MRP is that the drivers already implement SWITCHDEV_ATTR_ID_PORT_STP_STATE and already in SW we update the port STP state.
