commit ce00322c2365e1f7b0312f2f493539c833465d97 upstream. pcie_flr() starts a Function Level Reset (FLR), waits 100ms (the maximum time allowed for FLR completion by PCIe r5.0, sec 6.6.2), and waits for the FLR to complete. It assumes the FLR is complete when a config read returns valid data. When we do an FLR on several Huawei Intelligent NIC VFs at the same time, firmware on the NIC processes them serially. The VF may respond to config reads before the firmware has completed its reset processing. If we bind a driver to the VF (e.g., by assigning the VF to a virtual machine) in the interval between the successful config read and completion of the firmware reset processing, the NIC VF driver may fail to load. Prevent this driver failure by waiting for the NIC firmware to complete its reset processing. Not all NIC firmware supports this feature.

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.
