Ethernet frames can be extracted or injected to or from the device's DDR memory. There is one channel for injection and one channel for extraction. Each of these channels contain a linked list of DCBs which contains DB. The DCB contains only 1 DB for both the injection and extraction. Each DB contains a frame. Every time when a frame is received or transmitted an interrupt is generated. It is not possible to use both the FDMA and the manual injection/extraction of the frames. Therefore the FDMA has priority over the manual because of better performance values.

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.
