[ Upstream commit ddc49acb659a2d8bfc5fdb0de0ef197712c11d75 ] We already have a workaround for a couple of switches whose internal PHYs only have the Marvel OUI, but no model number. We detect such PHYs and give them the 6390 ID as the model number. However the mv88e6161 has two SERDES interfaces in the same address range as its internal PHYs. These suffer from the same problem, the Marvell OUI, but no model number. As a result, these SERDES interfaces were getting the same PHY ID as the mv88e6390, even though they are not PHYs, and the Marvell PHY driver was trying to drive them. Add a special case to stop this from happen. Reported-by: Chris Healy <Chris.Healy@zii.aero> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

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.
