When stmmac_ethtool_op_get_eee() is called, stmmac sets the tx_lpi_timer and tx_lpi_enabled members, and then calls into phylink and thus phylib. phylib overwrites these members. phylib will also cause a link down/link up transition when settings that impact the MAC have been changed. Convert stmmac to use the tx_lpi_timer setting in struct phy_device, updating priv->tx_lpi_timer each time when the link comes up, rather than trying to maintain this user setting itself. We initialise the phylib tx_lpi_timer setting by doing a get_ee-modify-set_eee sequence with the last known priv->tx_lpi_timer value. In order for this to work correctly, we also need this member to be initialised earlier. As stmmac_eee_init() is no longer called outside of stmmac_main.c, make it static.

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.
