Subject[PATCH net-next v4 02/12] bridge: uapi: mrp: Extend MRP attributes for MRP interconnect
Date
Extend the existing MRP netlink attributes to allow to configure MRP
Interconnect:

IFLA_BRIDGE_MRP_IN_ROLE - the parameter type is br_mrp_in_role which
contains the interconnect id, the ring id, the interconnect role(MIM
or MIC) and the port ifindex that represents the interconnect port.

IFLA_BRIDGE_MRP_IN_STATE - the parameter type is br_mrp_in_state which
contains the interconnect id and the interconnect state.

IFLA_BRIDGE_MRP_IN_TEST - the parameter type is br_mrp_start_in_test
which contains the interconnect id, the interval at which to send
MRP_InTest frames, how many test frames can be missed before declaring
the interconnect ring open and the period which represents for how long
to send MRP_InTest frames.
