This patch series extends the MRP with the MRA role.
A node that has the MRA role can behave as a MRM or as a MRC. In case there are
multiple nodes in the topology that has the MRA role then only one node can
behave as MRM and all the others need to be have as MRC. The node that has the
higher priority(lower value) will behave as MRM.
A node that has the MRA role and behaves as MRC, it just needs to forward the
MRP_Test frames between the ring ports but also it needs to detect in case it
stops receiving MRP_Test frames. In that case it would try to behave as MRM.

  bridge: mrp: Set the priority of MRP instance
  bridge: mrp: Add support for role MRA
