Mitch Williams c21bb711d0 iavf: restore MSI state on reset
commit 7e4dcc13965c57869684d57a1dc6dd7be589488c upstream.

If the PF experiences an FLR, the VF's MSI and MSI-X configuration will
be conveniently and silently removed in the process. When this happens,
reset recovery will appear to complete normally but no traffic will
pass. The netdev watchdog will helpfully notify everyone of this issue.

To prevent such public embarrassment, restore MSI configuration at every
reset. For normal resets, this will do no harm, but for VF resets
resulting from a PF FLR, this will keep the VF working.

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.
