Subject: [PATCH mlx5-next 00/12] mlx5 core generic EQ API for RDMA ODP

Hi,

This patchset is for mlx5-next shared branch, and will be applied there
once the review is done.

This patchset introduces mostly refactoring work and EQ related code updates to
allow moving the ODP rdma only logic from mlx5_core into mlx5 ib where it
belongs, and will allow future updates and optimizations for the rdma ODP
(On Demand Paging) feature to go only to rdma tree.

Patch #1: Fixes the offsets of stored irq affinity hints inside mlx5
irq info array.

Patch #2,3,4: Remove unused fields, code and logic

Patch #5: Move all EQ related logic from main.c to eq.c to allow clear
and seamless refactoring for creating generic EQ management API.

Patch #6: Create mlx5 core EQs in one place, in order to have one entry
point to call from main file.

Patch #7,8: Move EQ related structures into eq_table mlx5 structure and
make eq_table fields and logic private to eq.c file.

Patch #9,10: Create one generic EQ struct and use it in different
EQ types (usages) e.g. (Async, Command, FW pages, completion and ODP)
Introduce generic EQ API to allow creating Generic EQs regardless of
their types, will be uesd to create all mlx5 core EQs in mlx5_core and
ODP EQ in mlx5_ib.

Patch #11: Move ODP logic out from mlx5_core eq.c into mlx5 rdma driver.
odp.c file.

Patch #12: Make the trivial EQE access methods inline.

Thanks,
Saeed.
