[pull request][net-next 00/16] mlx5 updates 2021-07-24

Hi Dave and Jakub,

This series provides some refactoring to mlx5e RX resource management,
it is required for upcoming ADQ and TX lag hashing features.

The first two patches in this series :
  net/mlx5e: Prohibit inner indir TIRs in IPoIB
  net/mlx5e: Block LRO if firmware asks for tunneled LRO
Were supposed to go to net, but due to dependency and timing they were
included here.
I would appreciate it if you'd apply them to net and mark for -stable.

For more information please see tag log below.

Please pull and let me know if there is any problem.

Thanks,
Saeed.

  net/mlx5e: Use the new TIR API for kTLS (2021-07-26 09:50:41 -0700)

----------------------------------------------------------------
mlx5-updates-2021-07-24

This series aims to reduce coupling in mlx5e, particularly between RX
resources (TIRs, RQTs) and numerous code units that use them.

This refactoring is required for upcoming features, ADQ and TX lag
hashing.

The issue with the current code is that TIRs and RQTs are unmanaged,
different places all over the driver create, destroy, track and
configure them, often in an uncoordinated way. The responsibilities of
different units become vague, leading to a lot of hidden dependencies
between numerous units and tight coupling between them, which is prone
to bugs and hard to maintain.

The result of this refactoring is:

1. Creating a manager for RX resources, that controls their lifecycle
and provides a clear API, which restricts the set of actions that other
units can do.

2. Using object-oriented approach for TIRs, RQTs and RX resource
manager (struct mlx5e_rx_res).

3. Fixing a few bugs and misbehaviors found during the refactoring.

4. Reducing the amount of dependencies, removing hidden dependencies,
making them one-directional and organizing the code in clear abstraction
layers.

5. Explicitly exposing the remaining weird dependencies.

6. Simplifying and organizing code that creates and modifies TIRs and
RQTs.
