Generate a unique 128bit identifier for each host and pass that value to firmware in the INIT_HCA command if it reports the sw_owner_id capability. Each device bound to the mlx5_core driver will have the same software owner ID. In subsequent patches mlx5_core devices will be bound via a new VPort command so that they can operate together under a single InfiniBand device. Only devices that have the same software owner ID can be bound, to prevent traffic intended for one host arriving at another. The INIT_HCA command length was expanded by 128 bits. The command length is provided as an input FW commands. Older FW does not have a problem receiving this command in the new longer form.

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.
