Marvell PPv2 controller can be used to implement packet filtering based on the destination MAC address. This is already used to implement multicast filtering. This patch adds support for Unicast filtering. Filtering is based on so-called "TCAM entries" to implement filtering. Due to their limited number and the fact that these are also used for other purposes, we reserve 80 entries for both unicast and multicast filters. On top of the broadcast address, and each interface's own MAC address, we reserve 25 entries per port, 4 for unicast filters, 21 for multicast. Whenever unicast or multicast range for one port is full, the filtering is disabled and port goes into promiscuous mode for the given type of addresses.

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.
