Re: [PATCH v4 03/10] net/mlx5: Extract MLX5_SET/GET macros into mlx5_ifc_macros.h

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The newly extracted `mlx5_ifc_macros.h` header lacks necessary include directives for the types and macros it uses, violating the kernel's self-contained header rule.

net/mlx5: Extract MLX5_SET/GET macros into mlx5_ifc_macros.h

This commit extracts the MLX5_SET/GET macro family from device.h into a new
standalone header, mlx5_ifc_macros.h. The extraction allows VFIO selftests
to use these macros without pulling in the dependencies of device.h.

[Severity: Low]
Does this new header need to include its dependencies such as <linux/types.h>,
<linux/stddef.h>, <linux/build_bug.h>, and <asm/byteorder.h>?

Since the commit message mentions this header is intended for independent use
by VFIO selftests, without these includes, files that include this header
directly might fail to compile due to missing definitions for u32, offsetof,
BUILD_BUG_ON, and cpu_to_be32.
