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.
