014:  * 2003/03/18 - Amir Noam <amir.noam at intel dot com>
015:  *      - Added support for getting slave's speed and duplex via ethtool.
016:  *        Needed for 802.3ad and other future modes.
017:  *
018:  * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
019:  *              Shmulik Hen <shmulik.hen at intel dot com>
020:  *      - Enable support of modes that need to use the unique mac address of
021:  *        each slave.
022:  *
023:  * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
024:  *              Amir Noam <amir.noam at intel dot com>
025:  *      - Moved driver's private data types to bonding.h
026:  *
027:  * 2003/03/18 - Amir Noam <amir.noam at intel dot com>,
028:  *              Tsippy Mendelson <tsippy.mendelson at intel dot com> and
029:  *              Shmulik Hen <shmulik.hen at intel dot com>
030:  *      - Added support for IEEE 802.3ad Dynamic link aggregation mode.
031:  *
032:  * 2003/05/01 - Amir Noam <amir.noam at intel dot com>
033:  *      - Added ABI version control to restore compatibility between
034:  *        new/old ifenslave and new/old bonding.
035:  *
036:  * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
037:  *      - Code cleanup and style changes
038:  *
039:  * 2005/05/05 - Jason Gabler <jygabler at lbl dot gov>
040:  *      - added definitions for various XOR hashing policies
