With the move to using the Page Pool API for RX, rx copybreak was not showing any improvement in host CPU overhead, latency or bandwidth so the driver no longer makes use of the rx_copybreak setting. This patch removes the ethtool tuneable hooks to set and get the rx copybreak since they and now no-ops. Rx copybreak was the only tunable supported, so remove the set and get tunable callbacks all together.

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.
