Subject[PATCH net-next v4 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.
