Before PF asserting function reset, it should make sure that all its VFs have been ready, otherwise, it will cause some hardware errors. So this patch adds function hclge_func_reset_sync_vf() to synchronize VF before asserting PF function reset. For new firmware which supports command HCLGE_OPC_QUERY_VF_RST_RDY, we will try to query VFs' ready status within 30 seconds. And keep the old implementation for compatible with firmware which does not support this command.

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.
