Our initial VF control implementation was focused on providing a very minimal support for the VF_STATE_NOTIFY events just to meet GuC requirements, without tracking a VF state or doing any expected actions (like cleanup in case of the FLR notification). Try to improve this by defining set of VF state machines, each responsible for processing one activity (PAUSE, RESUME, STOP or FLR). All required steps defined by the VF state machine are then executed by the PF worker from the dedicated workqueue. Any external requests or notifications simply try to transition between the states to trigger a work and then wait for that work to finish. Some predefined default timeouts are used to avoid changing existing API calls, but it should be easy to extend the control API to also accept specific timeout values.

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 reStructuredText 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.
