Currently, the reset interrupt is cleared in the reset task, which
is too late. Since, when the hardware finish the previous reset,
it can begin to do a new global/IMP reset, if this new coming reset
type is same as the previous one, the driver will clear them together,
then driver can not get that there is another reset, but the hardware
still wait for the driver to deal with the second one.
So this patch clears PF's reset interrupt status in the
hclge_irq_handle(), the hardware waits for handshaking from
driver before doing reset, so the driver and hardware deal with reset
one by one.
BTW, when VF doing global/IMP reset, it reads PF's reset interrupt
register to get that whether PF driver's re-initialization is done,
since VF's re-initialization should be done after PF's. So we add
a new command and a register bit to do that. When VF receive reset
interrupt, it sets up this bit, and PF finishes re-initialization
send command to clear this bit, then VF do re-initialization.
Fixes:

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.
