Oleksij Rempel b7ffab29a8 net: bridge: switchdev: Improve error message for port_obj_add/del functions
Enhance the error reporting mechanism in the switchdev framework to
provide more informative and user-friendly error messages.

Following feedback from users struggling to understand the implications
of error messages like "failed (err=-28) to add object (id=2)", this
update aims to clarify what operation failed and how this might impact
the system or network.

With this change, error messages now include a description of the failed
operation, the specific object involved, and a brief explanation of the
potential impact on the system. This approach helps administrators and
developers better understand the context and severity of errors,
facilitating quicker and more effective troubleshooting.

Example of the improved logging:

[   70.516446] ksz-switch spi0.0 uplink: Failed to add Port Multicast
               Database entry (object id=2) with error: -ENOSPC (-28).
[   70.516446] Failure in updating the port's Multicast Database could
               lead to multicast forwarding issues.
[   70.516446] Current HW/SW setup lacks sufficient resources.

This comprehensive update includes handling for a range of switchdev
object IDs, ensuring that most operations within the switchdev framework
benefit from clearer error reporting.

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 reStructuredText 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.
