This patch reworks the MRP netlink interface. Before, each attribute represented a binary structure which made it hard to be extended. Therefore update the MRP netlink interface such that each existing attribute to be a nested attribute which contains the fields of the binary structures. In this way the MRP netlink interface can be extended without breaking the backwards compatibility. It is also using strict checking for attributes under the MRP top attribute.
