This patch restructures how VFs are configured, and resources allocated. Instead of freeing resources that were never allocated, and resetting empty VFs that have never been created - the new flow will just allocate resources for number of requested VFs based on the availability. During VFs initialization process, global interrupt is disabled, and rearmed after getting MSIX vectors for VFs. This allows immediate mailbox communications, instead of delaying it till later and VFs. PF communications resulted to using polling instead of actual interrupt. The issue manifested when creating higher number of VFs (128 VFs) per PF.

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.
