Use an i40e_stats array to handle the queue stats, instead of coding similar functionality separately. Because of how the queue stats are accessed on some kernels, we can't easily use i40e_add_ethtool_stats. Instead, implement a separate helper, i40e_add_queue_stats, which we'll use instead. This helper will correctly implement the u64_stats_fetch_begin_irq logic and allow retries until successful. We share the most complex code by re-using i40e_add_one_ethtool_stat. This logic additionally easily supports skipping disabled rings by using a ternary operator before calling the u64_stats_fetch_begin_irq() function, so that we correctly zero-out the stats values without having to perform two separate sections of code. This significantly reduces the boiler plate code in i40e_get_ethtool_stats, and helps keep the complex logic contained to as few functions as possible. With this patch, we've finally converted all the statistics to use the helpers and the i40e_stats function.

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.
