[PATCH rdma-next v4 0/3] Use RDMA adaptive moderation library

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@mellanox.com>

Hi,

This is RDMA part of previously sent DIM library improvements series
[1], which was pulled by Dave. It needs to be pulled to RDMA too as
a pre-requirements.

Changes since v3:
 * Renamed dim_owner to be priv
 * Added Sagi's ROBs
 * Removed casting of void pointer.

Changes since v2:
- renamed user-space knob from dim to adaptive-moderation (Sagi)
- some minor code clean ups (Sagi)
- Reordered patches to ensure that netlink expose is last in the series.
- Slightly cleaned commit messages
- Changed "bool use_cq_dim" flag to be bitwise to save space.

Changes since v1:
- added per ib device configuration knob for rdma-dim (Sagi)
- add NL directives for user-space / rdma tool to configure rdma dim
  (Sagi/Leon)
- use one header file for DIM implementations (Leon)
- various point changes in the rdma dim related code in the IB core
  (Leon)
- removed the RDMA specific patches form this pull request\

Thanks
