Currently VFs are only allowed to get 16, 4, and 1 queue pair by default, which require 17, 5, and 2 MSI-X vectors respectively. This is because each VF needs a MSI-X per data queue and a MSI-X for its other interrupt. The calculation is based on the number of VFs created, MSI-X available, and queue pairs available at the time of VF creation. Unfortunately the values above exclude 2 queue pairs when only 3 MSI-X are available to each VF based on resource constraints. The current calculation would default to 2 MSI-X and 1 queue pair. This is a waste of resources, so fix this by allowing 2 queue pairs per VF when there are between 2 and 5 MSI-X available per VF.

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.
