Add an auxiliary virtual bus to model the mlx4 driver structure. The code is added along the current custom device management logic. Subsequent patches switch mlx4_en and mlx4_ib to the auxiliary bus and the old interface is then removed. Structure mlx4_priv gains a new adev dynamic array to keep track of its auxiliary devices. Access to the array is protected by the global mlx4_intf mutex. Functions mlx4_register_device() and mlx4_unregister_device() are updated to expose auxiliary devices on the bus in order to load mlx4_en and/or mlx4_ib. Functions mlx4_register_auxiliary_driver() and mlx4_unregister_auxiliary_driver() are added to substitute mlx4_register_interface() and mlx4_unregister_interface(), respectively. Function mlx4_do_bond() is adjusted to walk over the adev array and re-adds a specific auxiliary device if its driver sets the MLX4_INTFF_BONDING flag.

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.
