[ Upstream commit879626e3a5] Note in the databook - Section 4.4 - EEE : " The EEE feature is not supported when the MAC is configured to use the TBI, RTBI, SMII, RMII or SGMII single PHY interface. Even if the MAC supports multiple PHY interfaces, you should activate the EEE mode only when the MAC is operating with GMII, MII, or RGMII interface." Applying this restriction solves a stability issue observed on Amlogic gxl platforms operating with RMII interface and the internal PHY.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
