This change implements retrieving all the error counters from the PHY. The counters require that the RxErrCnt register (0x0014) be read first, after which copies of the counters are latched into the registers. This ensures that all registers read after RxErrCnt are synchronized at the moment that they are read. The counter values need to be accumulated by the driver, as each time that RxErrCnt is read, the values that are latched are the ones that have incremented from the last read.

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.
