Add an option to get migration data size by introducing a new migration feature named VFIO_DEVICE_FEATURE_MIG_DATA_SIZE. Upon VFIO_DEVICE_FEATURE_GET the estimated data length that will be required to complete STOP_COPY is returned. This option may better enable user space to consider before moving to STOP_COPY whether it can meet the downtime SLA based on the returned data. The patch also includes the implementation for mlx5 and hisi for this new option to make it feature complete for the existing drivers in this area.

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.
