[PATCH rdma-next v1 00/11] RAW format dumps through RDMAtool

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

Changelog:
v1:
 * Maor dropped controversial change to dummy interface.
v0: https://lore.kernel.org/linux-rdma/20200513095034.208385-1-leon@kernel.org

Hi,

The following series adds support to get the RDMA resource data in RAW
format. The main motivation for doing this is to enable vendors to return
the entire QP/CQ/MR data without a need from the vendor to set each field
separately.

Thanks

Maor Gottlieb (11):
  net/mlx5: Export resource dump interface
  net/mlx5: Add support in query QP, CQ and MKEY segments
  RDMA/core: Don't call fill_res_entry for PD
  RDMA: Add dedicated MR resource tracker function
  RDMA: Add dedicated CQ resource tracker function
  RDMA: Add dedicated QP resource tracker function
  RDMA: Add dedicated CM_ID resource tracker function
  RDMA: Add support to dump resource tracker in RAW format
  RDMA/mlx5: Add support to get QP resource in raw format
  RDMA/mlx5: Add support to get CQ resource in RAW format
  RDMA/mlx5: Add support to get MR resource in RAW format

[PATCH mlx5-next v1 01/11] net/mlx5: Export resource dump interface

[Leon Romanovsky]

From: Maor Gottlieb <maorg@mellanox.com>

Export some of the resource dump API, so it could be
used by the mlx5_ib driver as well.
