RDMA/nldev: Provide global resource utilization
Expose through the netlink interface the global per-device utilization of the supported object types. Provide both dumpit and doit callbacks. As an example of possible output from rdmatool for system with 5 mlx5 cards: $ rdma res 1: mlx5_0: qp 4 cq 5 pd 3 2: mlx5_1: qp 4 cq 5 pd 3 3: mlx5_2: qp 4 cq 5 pd 3 4: mlx5_3: qp 2 cq 3 pd 2 5: mlx5_4: qp 4 cq 5 pd 3 Reviewed-by: Mark Bloch <markb@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Reviewed-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
