When driver queries the register number of mac statistics from firmware,
the old firmware runs in device version V2 only returns number of valid
registers, not include number of three reserved registers among of them.
It cause driver doesn't record the last three data when query mac
statistics.
To fix this problem, driver never query register number in device version
V2 and set it to a fixed value which include three reserved registers.

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.
