Michael Chan cc72f3b1fe bnxt_en: Fix possible corrupted NVRAM parameters from firmware response.
In bnxt_find_nvram_item(), it is copying firmware response data after
releasing the mutex.  This can cause the firmware response data
to be corrupted if the next firmware response overwrites the response
buffer.  The rare problem shows up when running ethtool -i repeatedly.

Fix it by calling the new variant _hwrm_send_message_silent() that requires
the caller to take the mutex and to release it after the response data has
been copied.

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
