The mlx5e_alloc_unit union is conveniently used to store arrays of pointers to struct page or struct xdp_buff (for xsk). The union is currently expected to have the size of a pointer for xsk batch allocations to work. This is conveniet for the current state of the code but makes it impossible to add a structure of a different size to the alloc unit. A further patch in the series will add the mlx5e_frag_page struct for which the described size constraint will no longer hold. This change removes the usage of mlx5e_alloc_unit union for legacy rq: - A union of arrays is introduced (mlx5e_alloc_units) to replace the array of unions to allow structures of different sizes. - Each fragment has a pointer to a unit in the mlx5e_alloc_units array.

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.
