Dawid Osuchowski 0bc1f727d7 ice: fix VF interrupts cleanup 
[ Upstream commit fb09688209 ]

When a virtual function sends an IRQ map command, the PF will set up
interrupts according to that request. However, because these interrupts are
never reset, the next time Virtual Function initializes, the interrupts are
still enabled for a given VF, which leads to performance degradation in
certain cases due to interrupts being unexpectedly enabled and thus causing
interrupt floods.

README 

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.
