[ Upstream commit d089d69cc1 ]
This patch fixes a FLR bug on the SNET DPU rev 1 by setting the
PCI_DEV_FLAGS_NO_FLR_RESET flag.
As there is a quirk to avoid FLR (quirk_no_flr), I added a new quirk
to check the rev ID before calling to quirk_no_flr.
Without this patch, a SNET DPU rev 1 may hang when FLR is applied.

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.
