    15	 * 2003/03/18 - Amir Noam <amir.noam at intel dot com>
    16	 *	- Added support for getting slave's speed and duplex via ethtool.
    17	 *	  Needed for 802.3ad and other future modes.
    18	 *
    19	 * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
    20	 *		Shmulik Hen <shmulik.hen at intel dot com>
    21	 *	- Enable support of modes that need to use the unique mac address of
    22	 *	  each slave.
    23	 *
    24	 * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
    25	 *		Amir Noam <amir.noam at intel dot com>
    26	 *	- Moved driver's private data types to bonding.h

    30	 *		Shmulik Hen <shmulik.hen at intel dot com>
    31	 *	- Added support for IEEE 802.3ad Dynamic link aggregation mode.
    32	 *
    33	 * 2003/05/01 - Amir Noam <amir.noam at intel dot com>
    34	 *	- Added ABI version control to restore compatibility between
    35	 *	  new/old ifenslave and new/old bonding.
    36	 *
    37	 * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
    38	 *	- Code cleanup and style changes
    39	 *
    40	 * 2005/05/05 - Jason Gabler <jygabler at lbl dot gov>
    41	 *      - added definitions for various XOR hashing policies
