[ Upstream commit 08501970472077ed5de346ad89943a37d1692e9b ]
After spawning max VFs on a PF, some VFs were not getting resources and
their MAC addresses were 0. This was caused by PF sleeping before flushing
HW registers which caused VIRTCHNL_VFR_VFACTIVE to not be set in time for
VF.
Fix by adding a sleep after hw flush.
Fixes: e4b433f4a741 ("i40e: reset all VFs in parallel when rebuilding PF")

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.
