- * DOC: Introduction
- *
- * This header is intended to be exported to userspace,
- * to make the structures and enumerations available to userspace
- * applications. This means that all data types should be exportable.
- *
- * When rt2x00 is compiled with debugfs support enabled,
- * it is possible to capture all data coming in and out of the device
- * by reading the frame dump file. This file can have only a single reader.
- * The following frames will be reported:
- * - All incoming frames (rx)
- * - All outgoing frames (tx, including beacon and atim)
- * - All completed frames (txdone including atim)
- *
- * The data is send to the file using the following format:
- *
- * [rt2x00dump header][hardware descriptor][ieee802.11 frame]
- *
- * rt2x00dump header: The description of the dumped frame, as well as
- * additional information useful for debugging. See &rt2x00dump_hdr.
- * hardware descriptor: Descriptor that was used to receive or transmit
- * the frame.
- * ieee802.11 frame: The actual frame that was received or transmitted.

- * struct rt2x00dump_hdr - Dump frame header
- *
- * Each frame dumped to the debugfs file starts with this header
- * attached. This header contains the description of the actual
- * frame which was dumped.
- *
- * New fields inside the structure must be appended to the end of
- * the structure. This way userspace tools compiled for earlier
- * header versions can still correctly handle the frame dump
- * (although they will not handle all data passed to them in the dump).
- *
- * @version: Header version should always be set to %DUMP_HEADER_VERSION.
- * This field must be checked by userspace to determine if it can
- * handle this frame.
- * @header_length: The length of the &rt2x00dump_hdr structure. This is
- * used for compatibility reasons so userspace can easily determine
- * the location of the next field in the dump.
- * @desc_length: The length of the device descriptor.
- * @data_length: The length of the frame data (including the ieee802.11 header.

- * @chip_rev: Chipset revision
