[ Upstream commit 26e42ec7712d392d561964514b1f253b1a96f42d ]
If PF (Physical Function) has SFs (Sub-Functions), since the SFs are not
taking part in the synchronization flow, sync reset can lead to fatal
error on the SFs, as the function will be closed unexpectedly from the
SF point of view.
Add a check to prevent sync reset when there are SFs on a PF device
which is not ECPF, as ECPF is teardowned gracefully before reset.
Fixes: 92501fa6e4 ("net/mlx5: Ack on sync_reset_request only if PF can do reset_now")

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.
