This patch series extends existing MRP to add support for interconnect ring. An
interconnect ring is a ring that connects 2 rings. In this way is possible to
connect multiple rings. Each interconnect ring is form of 4 nodes, in which 3
have the role MIC(Media Redundancy Interconnect Client) and on

Extend switchdev API to add support for MRP interconnect. The HW is
notified in the following cases:
SWITCHDEV_OBJ_ID_IN_ROLE_MRP: This is used when the interconnect role
of the node changes. The supported roles are MIM and MIC.
SWITCHDEV_OBJ_ID_IN_STATE_MRP: This is used when the interconnect
Implement the MRP API for interconnect switchdev. Similar with the other
br_mrp_switchdev function, these function will just eventually call the
switchdev functions: switchdev_port_obj_add/del.

This patch renames the function br_mrp_port_open to
br_mrp_ring_port_open. In this way is more clear that a ring port lost
the continuity because there will be also a br_mrp_in_port_open.

This patch adds a new flag(BR_MRP_LOST_IN_CONT) to the net bridge
ports. This bit will be set when the port lost the continuity of
MRP_InTest frames.

case there is no MRP interconnect on the node then the role will be

This patch extends the existing MRP netlink interface with the following
attributes: IFLA_BRIDGE_MRP_IN_ROLE, IFLA_BRIDGE_MRP_IN_STATE and
IFLA_BRIDGE_MRP_START_IN_TEST. These attributes are similar with their
ring attributes but they apply to the interconnect port.

Thie patch adds support for MRP Interconnect. Similar with the MRP ring,
if the HW can't generate MRP_InTest frames, then the SW will try to
generate them. And if also the SW fails to generate the frames then an
error is return to userspace.
The forwarding/termination of MRP_In frames is happening
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
