This patch adds support for vfio_pci driver for mlx5 devices. It uses vfio_pci_core to register to the VFIO subsystem and then implements the mlx5 specific logic in the migration area. The migration implementation follows the definition from uapi/vfio.h and uses the mlx5 VF->PF command channel to achieve it. This patch implements the suspend/resume flows.

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.
