Leszek Polak 65a9dedc11 net: phy: marvell: Add errata section 5.1 for Alaska PHY
As per Errata Section 5.1, if EEE is intended to be used, some register
writes must be done once after every hardware reset. This patch now adds
the necessary register writes as listed in the Marvell errata.

Without this fix we experience ethernet problems on some of our boards
equipped with a new version of this ethernet PHY (different supplier).

The fix applies to Marvell Alaska 88E1510/88E1518/88E1512/88E1514
Rev. A0.

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.
