> Subject: [PATCH] common/mlx5: fix CPU detection for PCI relaxed ordering
> 
> The detection of the CPU was done in a constructor and shared in a global
> variable.
> 
> This variable may not be visible in the net PMD because it was not exported
> as part of the .map file.
> It is fixed by exporting a function, which is cleaner than a variable.
> 
> By checking the CPU only at the first call of the function, doing the check in a
> constructor becomes useless.
> Note: the priority of the constructor was probably irrelevant.
> 
> At the same time, the comments are reworded or dropped if useless.
> 
> Fixes: 4c204fe5e5d2 ("common/mlx5: disable relaxed ordering in unsuitable
> CPUs")
