The MAC driver changes its EEE hardware configuration in its adjust_link callback. This is called when auto-neg completes. Disabling EEE via eee_enabled false will trigger an autoneg, and as a result the adjust_link callback will be called with phydev->enable_tx_lpi set to false. Similarly, eee_enabled set to true and with a change of advertised link modes will result in a new autoneg, and a call the adjust_link call. If set_eee is called with only a change to tx_lpi_enabled which does not trigger an auto-neg, it is necessary to call the adjust_link callback so that the MAC is reconfigured to take this change into account. When setting phydev->enable_tx_lpi, take both eee_enabled and tx_lpi_enabled into account, so the MAC drivers just needs to act on phydev->enable_tx_lpi and not the whole EEE configuration. The same check should be done for tx_lpi_timer too.

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.
