Add an u64 hardware timestamping statistics structure for each ocelot port. Export a function from the common switch library for reporting them to ethtool. This is called by the ocelot switchdev front-end for now. Note that for the switchdev driver, we report the one-step PTP packets as unconfirmed, even though in principle, for some transmission mechanisms like FDMA, we may be able to confirm transmission and bump the "pkts" counter in ocelot_fdma_tx_cleanup() instead. I don't have access to hardware which uses the switchdev front-end, and I've kept the implementation simple.

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 reStructuredText 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.
