The Microchip/SMSC LAN8710/LAN8720 PHYs need (according to their datasheet [1]) a continuous REF_CLK when configured to "REF_CLK In Mode". Therefore set the PHY_RST_AFTER_CLK_EN flag for those PHYs to let the ETH driver reset them after the REF_CLK is enabled.

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.
