On P5_PLUS chips and later, the NQ rings have subrings for RX and TX completions respectively. These subrings are passed to the poll function instead of the base NQ, but each ring carries its own copy of the software ring statistics. For stats to be conveniently accessible in __bnxt_poll_work(), the statistics memory should either be shared between the NQ and its subrings or the subrings need to be included in the ethtool stats aggregation logic. This patch opts for the former, because it's more efficient and less confusing having the software statistics for a ring exist in a single place. Before this patch, the counter will not be displayed if the "wrong" cpr->sw_stats was used to increment a counter.

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.
