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 in the kernel and is done by MRP instances.
