Aleksandr Loktionov 67b7f73bbe i40e: Revert "i40e: don't report link up for a VF who hasn't enabled queues" 
[ Upstream commit f559a356043a55bab25a4c00505ea65c50a956fb ]

This reverts commit 2ad1274fa3

VF queues were not brought up when PF was brought up after being
downed if the VF driver disabled VFs queues during PF down.
This could happen in some older or external VF driver implementations.
The problem was that PF driver used vf->queues_enabled as a condition
to decide what link-state it would send out which caused the issue.

Remove the check for vf->queues_enabled in the VF link notify.
Now VF will always be notified of the current link status.
Also remove the queues_enabled member from i40e_vf structure as it is
not used anymore. Otherwise VNF implementation was broken and caused
a link flap.

The original commit was a workaround to avoid breaking existing VFs though
it's really a fault of the VF code not the PF. The commit should be safe to
revert as all of the VFs we know of have been fixed. Also, since we now
know there is a related bug in the workaround, removing it is preferred.

README 

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.
