It's kind of late by now, but I'd wish these were contained in a nested MRP attribute. :)
Horatiu, do you expect to have many more MRP attributes outside of MRP netlink code?
Perhaps we should at least dump them only for MRP-aware ports, that should be easy.
They make no sense outside of MRP anyway, but increase the size of the dump for all
right now.
