Ethernet switch on the MDIO bus have historically performed their own
handling of the GPIO reset line. The resent patch to have the MDIO
core handle the reset has broken the switch drivers, in that they
cannot claim the GPIO. Some switch drivers need more control over the
GPIO line than what the MDIO core provides. So restore the historical
behaviour by only performing a reset of PHYs, not switches.

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.
