Vivien Didelot says: ==================== net: dsa: define port types The DSA code currently has 3 bitmaps in the dsa_switch structure: cpu_port_mask, dsa_port_mask and enabled_port_mask. They are used to store the type of each switch port. This dates back from when DSA didn't have a dsa_port structure to hold port-specific data. The dsa_switch structure is mainly used to communicate with DSA drivers and must not contain such static data parsed from DTS or pdata, which belongs the DSA core structures, such as dsa_switch_tree and dsa_port. Also the enabled_port_mask is misleading, often misinterpreted as the complement of disabled ports (thus including DSA and CPU ports), while in fact it only masks the user ports. A port can be of 3 types when it is not unused: "cpu" (interfacing with a master device), "dsa" (interconnecting with another "dsa" port from another switch chip), or "user" (user-facing port.) This patchset first fixes the usage of DSA port type helpers, then defines the DSA_PORT_TYPE_UNUSED, DSA_PORT_TYPE_CPU, DSA_PORT_TYPE_DSA, and DSA_PORT_TYPE_USER port types, and finally removes the misleading port bitmaps. ==================== 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.
