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. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEGhZs6bAKwk/OTgTpSD+KveBX+j4FAmD+5+EACgkQSD+KveBX +j6l/Qf9FHU8xRCBW0Bn4Ja0CnS/C3MJMIBTRbe+Qq2noj6qr8y6ut8Z7jV3hGaw dvcA6bVxpWPsqrY5CX4errfo2T4QiAsYhIeXrE2liCZsMUeYeZLusAYquks0oo57 ai2FnihMvL5Xf9U2r+aAeT4dxpQBJ7ANON+b+ZRCFjwRl8CZkd7i4pnifLYpptye d6de6QSZkvxc818homiALdu0VH8HOBZALzfMI9y2Oh9peW+irc2UhEoThukD5VCD Turm6WBQ4xteQq3uNKebbqg0cEevyQjHoUmBg799xD0tHzFbSp+kV3ivHKxsksUF sOBdEumQjDc6J22uTnA086dIStN7sA== =jxI/ -----END PGP SIGNATURE----- Merge tag 'mlx5-updates-2021-07-24' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux 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.

Saeed Mahameed says: ==================== mlx5 updates 2021-07-24 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
