Hardware can sometimes not generate NQ MSIX with a single pending CP ring entry. This seems to always happen at the last entry of the CP ring before it wraps. Add logic to check all the CP rings for pending entries without the CP ring consumer index advancing. Calling HWRM_DBG_RING_INFO_GET to read the context of the CP ring will flush out the NQ entry and MSIX. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

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.
