bridge: mrp: Add support for role MRA
A node that has the MRA role, it can behave as MRM or MRC. Initially it starts as MRM and sends MRP_Test frames on both ring ports. If it detects that there are MRP_Test send by another MRM, then it checks if these frames have a lower priority than itself. In this case it would send MRP_Nack frames to notify the other node that it needs to stop sending MRP_Test frames. If it receives a MRP_Nack frame then it stops sending MRP_Test frames and starts to behave as a MRC but it would continue to monitor the MRP_Test frames send by MRM. If at a point the MRM stops to send MRP_Test frames it would get the MRM role and start to send MRP_Test frames. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.
