Fix a bug in the way we handled VF queues, by always showing stats for the maximum number of queues, even if they aren't allocated. It is not safe to change the number of strings reported to ethtool, as grabbing statistics occurs over multiple ethtool ops for which the rtnl_lock() cannot be held the entire time. Avoid this by always reporting queue stats for the maximum number of queues in the netdevice. Share some of the helper functionality for adding stats with the PF code in i40e_ethtool_stats.h This should reduce the chance of potential future bugs, and make adding new statistics easier. Note for the queue stats, unlike the PF driver we do not keep an array of queue pointers, but an array of queues, so care must be taken to avoid accessing queue memory that hasn't yet been allocated.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
