[RFC iproute2 6/8] rdma: add stubs for future objects

Leon Romanovsky
2017-05-04T18:02:44Z

From: Leon Romanovsky <leonro@mellanox.com>

The following objects (monitor, providers, stats and protocols) are not
implemented yet, however it is worth to place their stubs in the code.

This will serve as an initial starting point for other developers to
extend RDMA tool.
