As recommended by Azure host team, the bytes 4, 5 have more uniqueness (info entropy) than bytes 8, 9 so use them as the PCI domain numbers. On older hosts, bytes 4, 5 can also be used -- no backward compatibility issues are introduced and the chance of collision is greatly reduced. In the rare cases of collision, the driver code detects and finds another number that is not in use.

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.
