Provide an option to change the net namespace of a rdma device through a
netlink command. When multiple rdma devices exists in a system, and when
containers are used, this will limit rdma device visibility to a specified
net namespace.
An example command to change net namespace of mlx5_1 device to the
previously created net namespace 'foo' is:
$ ip netns add foo
$ rdma dev set mlx5_1 netns foo
