Sriharsha Basavapatna a36d9bdc19 PCI: Add ACS quirk for Broadcom BCM57414 NIC
commit db2f77e2bd99dbd2fb23ddde58f0fae392fe3338 upstream.

The Broadcom BCM57414 NIC may be a multi-function device.  While it does
not advertise an ACS capability, peer-to-peer transactions are not possible
between the individual functions, so it is safe to treat them as fully
isolated.

Add an ACS quirk for this device so the functions can be in independent
IOMMU groups and attached individually to userspace applications using
VFIO.

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.
