When EEE is disabled, we call stmmac_set_eee_lpi_timer(..., 0). For dwmac4, this will result in LPIATE being cleared, but LPIEN and LPITXA being set, causing LPI mode to be signalled (if it wasn't before). For others MACs, stmmac_set_eee_lpi_timer() does nothing, which means that LPI mode will continue to be signalled despite the expectation for it to be disabled. In both cases, LPI mode will be terminated when the transmitter has a packet to send, and LPIEN will be cleared by hardware. Call stmmac_reset_eee_mode() to ensure that LPI mode is disabled when EEE mode is requested to be disabled.

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.
