Add new nested netlink attribute to configure the MRP. These attributes are used by the userspace to add/delete/configure MRP instances and by the kernel to notify the userspace when the MRP ring gets open/closed. MRP nested attribute has the following attributes: IFLA_BRIDGE_MRP_INSTANCE - the parameter type is br_mrp_instance which contains the instance id, and the ifindex of the two ports. The ports can't be part of multiple instances. This is used to create/delete MRP instances. IFLA_BRIDGE_MRP_PORT_STATE - the parameter type is u32. Which can be forwarding, blocking or disabled. IFLA_BRIDGE_MRP_PORT_ROLE - the parameter type is br_mrp_port_role which contains the instance id and the role. The role can be primary or secondary. IFLA_BRIDGE_MRP_RING_STATE - the parameter type is br_mrp_ring_state which contains the instance id and the state. The state can be open or closed. IFLA_BRIDGE_MRP_RING_ROLE - the parameter type is br_mrp_ring_role which contains the instance id and the ring role. The role can be MRM or MRC. IFLA_BRIDGE_MRP_START_TEST - the parameter type is br_mrp_start_test which contains the instance id, the interval at which to send the MRP_Test frames, how many test frames can be missed before declaring the ring open and the period which represent for how long to send the test frames. Also add the file include/uapi/linux/mrp_bridge.h which defines all the types used by MRP that are also needed by the userpace.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
