[RFC net-next v3 05/10] net: bridge: mrp: Update MRP interface to add switchdev support

[Horatiu Vultur]

Extend the MRP interface to allow switchdev support. The following functions are
added:

br_mrp_port_switchdev_add - this corresponds to the function br_mrp_add_port,
  and will notify the HW that a port is added to a MRP ring. The function gets
  as parameter the port and the ID of the ring.

br_mrp_port_switchdev_del - this corresponds to the function br_mrp_del_port
  and will notify the HW that a port is removed from a MRP ring. The function
  gets as parameter the port and the ID of the ring.

br_mrp_port_switchdev_set_state - this corresponds to the function
  br_mrp_port_state. It would notify the HW if it should block or not non-MRP
  frames.

br_mrp_port_switchdev_set_port - this corresponds to the function
  br_mrp_port_role. It would set the port role, primary or secondary.

br_mrp_switchdev_set_role - this corresponds to the function br_mrp_ring_role
  and would set one of the role MRM or MRC.

br_mrp_switchdev_set_ring_state - this corresponds to the function
  br_mrp_ring_state and would set the ring to be open or closed.

br_mrp_switchdev_send_ring_test - this corresponds to the function
  br_mrp_start_test. This will notify the HW to start or stop generating
  MRP_Test frames. Value 0 for the interval parameter means to stop generating
  the frames.
