Set the length limit for the receive descriptor buffer and transmit descriptor buffer based on the controller type. The values used are called out in the controller datasheets as a 'Note:' in the RDLEN and TDLEN register descriptions. This allows the user to use ethtool to allocate larger descriptor buffers in the case where data is received or transmitted too quickly for the driver to keep up.

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.
