VLAN aware Marvell chips can program 802.1Q VLAN membership as well as 802.1s per VLAN Spanning Tree state using the same 3 VTU Data registers. Some chips such as 88E6185 use different Data registers offsets for ports state and membership, and program them in a single operation. Other chips such as 88E6352 use the same register layout but program them in distinct operations (an indirect table is used for 802.1s.) Newer chips such as 88E6390 use the same offsets for both state and membership in distinct operations, thus require multiple data accesses. To correctly abstract this, split the "data" structure member of mv88e6xxx_vtu_entry in two "state" and "member" members, before adding VTU support for newer chips.

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.
