    Subject[PATCH net-next 04/12] bridge: mrp: Extend br_mrp for MRP interconnect
    Date
    This patch extends the 'struct br_mrp' to contain information regarding
    the MRP interconnect. It contains the following:
    - the interconnect port 'i_port', which is NULL if the node doesn't have
    a interconnect role
    - the interconnect id, which is similar with the ring id, but this field
    is also part of the MRP_InTest frames.
    - the interconnect role, which can be MIM or MIC.
    - the interconnect state, which can be open or closed.
    - the interconnect delayed_work for sending MRP_InTest frames and check
    for lost of continuity.
