The SW currently saves local buffer ownership when setting
the buffer.
This means that the SW assumes it has ownership of the buffer
after the command is set.
If setting the buffer fails and we remain in FW ownership,
the local buffer ownership state incorrectly remains as SW-owned.
This leads to incorrect behavior in subsequent PFC commands,
causing failures.
Instead of saving local buffer ownership in SW,
query the FW for buffer ownership when setting the buffer.
This ensures that the buffer ownership state is accurately
reflected, avoiding the issues caused by incorrect ownership
states.

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.
