There is some NTB hardware, which can combine more than just two domains over NTB. For instance, some IDT PCIe-switches can have NTB-functions activated on more than two-ports. The different domains are distinguished by ports they are connected to. So the new port-related methods are added to the NTB API: ntb_port_number() - return local port ntb_peer_port_count() - return number of peers local port can connect to ntb_peer_port_number(pdix) - return port number by it index ntb_peer_port_idx(port) - return port index by it number Current test-drivers aren't changed much. They still support two-ports devices for the time being while multi-ports hardware drivers aren't added. By default port-related API is declared for two-ports hardware. So corresponding hardware drivers won't need to implement it. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
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.
