[ Upstream commitc7062aaee0] Make the upper bound on rx_copybreak tighter, by making sure it is smaller than the minimum of mtu and ENA_PAGE_SIZE. With the current upper bound of mtu, rx_copybreak can be larger than a page. Such large rx_copybreak will not bring any performance benefit to the user and therefore makes no sense. In addition, the value update was only reflected in the adapter structure, but not applied for each ring, causing it to not take effect.

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.
