When a Core/Global/IMP reset occurs, the hardware sets the reset status register of all PF/VF and reports a reset interrupt to all PF/VF and firmware. When receiving the reset interrupt: 1. The firmware will wait for 100 ms before resetting the hardware and clear the reset status register of all PF when hardware reset is done. 2. The PF/VF driver needs to down the netdev within 100 ms and then wait for hardware reset to finish. 3. After firmware clearing the reset status register of all PF, the PF driver reinitializes the hardware and clear the reset status register of it's VF. 4. After PF driver clearing the reset status register of VF, the VF driver reinitializes the hardware. This patch mainly add handling for the step 4.

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.
