We want to introduce elements kept in ocelot->stats that aren't exposed to the unstructured ethtool -S (so they won't have their name populated), but are otherwise checked for 32-bit wraparounds by ocelot_port_update_stats(). This isn't possible today because ocelot_prepare_stats_regions() skips over ocelot_stat_layout elements with no name. Now that we've changed struct ocelot_stat_layout to keep the absolute register address rather than the offset relative to SYS_CNT, we can make use of the unpopulated "reg" value of 0 to mean that the counter isn't present on the current switch revision, and skip it from the preparation of bulk regions.

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.
