This patch introduces the "Logical Port Number" which is similar to the "Port Number" in that it enumerates the ports in the system. The original (or Physical) "Port Number" can be any number used by the hardware to uniquely identify a port in the system. The "Logical Port Number" enumerates all ports in the system from 0 to the number of ports minus one. For example a system with 5 ports might have the following port numbers which would be enumerated thusly: Port Number: 1 2 5 7 116 Logical Port Number: 0 1 2 3 4 The logical port number is useful when calculating which resources to use for which peers. So we thus define two helper functions: ntb_logical_port_number() and ntb_peer_logical_port_number() which provide the "Logical Port Number" for the local port and any peer respectively.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
