Extend MRP to support LC mode(link check) for the interconnect port. This applies only to the interconnect ring. Opposite to RC mode(ring check) the LC mode is using CFM frames to detect when the link goes up or down and based on that the userspace will need to react. One advantage of the LC mode over RC mode is that there will be fewer frames in the normal rings. Because RC mode generates InTest on all ports while LC mode sends CFM frame only on the interconnect port. All 4 nodes part of the interconnect ring needs to have the same mode. And it is not possible to have running LC and RC mode at the same time on a node. Whenever the MIM starts it needs to detect the status of the other 3 nodes in the interconnect ring so it would send a frame called InLinkStatus, on which the clients needs to reply with their link status. This patch adds InLinkStatus frame type and extends existing rules on how to forward this frame.

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.
