MT7530 is a 7-ports Gigabit Ethernet Switch that could be found on Mediatek router platforms such as MT7623A or MT7623N platform which includes 7-port Gigabit Ethernet MAC and 5-port Gigabit Ethernet PHY. Among these ports, The port from 0 to 4 are the user ports connecting with the remote devices while the port 5 and 6 are the CPU ports connecting into Mediatek Ethernet GMAC. For port 6, it can communicate with the CPU via Mediatek Ethernet GMAC through either the TRGMII or RGMII which could be controlled by phy-mode in the dt-bindings to specify which mode is preferred to use. And for port 5, only RGMII can be specified. However, currently, only port 6 is being supported in this DSA driver. The driver is made with the reference to qca8k and other existing DSA driver. The most of the essential callbacks of the DSA are already support in the driver, including tag insert for user port distinguishing, port control, bridge offloading, STP setup and ethtool operation to allow DSA to model each user port into a standalone netdevice as the other DSA driver had done.

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.
