During firmware crash recovery, it is possible for firmware to respond to stale HWRM commands that have already timed out. Because response buffers may be reused, any out of sequence responses need to be ignored and only the matching seq_id should be accepted. Also, READ_ONCE should be used for the reads from the DMA buffer to ensure that the necessary loads are scheduled.

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.
