The mlx5 driver dumps the entire CQE buffer by default for few syndromes. Some syndromes are expected due to the application behavior [ex: MLX5_CQE_SYNDROME_REMOTE_ACCESS_ERR, MLX5_CQE_SYNDROME_REMOTE_OP_ERR and MLX5_CQE_SYNDROME_LOCAL_PROT_ERR]. Hence, for these syndromes, the patch converts the log level from KERN_WARNING to KERN_DEBUG. This enables the application to get the CQE buffer dump by changing to KERN_DEBUG level as and when needed.

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.
