Linux kernel source tree
1fe7bc109e
One of the parameters that is retrieved/printed as a response to
devlink health diagnostics for rx reporter is the RQ SW state.
It's printed as a bitmap decimal number. Printing it as bitmap is
problematic and non informative.
In addition User can't count on SW state without accessing the kernel
sources (mlx5e rq state enum in en.h).
This patch prints RQ SW state in a textual representation, as a key:
value pairs, where disabled rq states will appear as '0' and enabled
ones will appear as '1'.
See below the generated output for rx health diagnostics devlink
command:
$ devlink health diagnose auxiliary/mlx5_core.eth.0/65535 reporter rx

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.
