  14  * 2003/03/18 - Amir Noam <amir.noam at intel dot com>
  15  *      - Added support for getting slave's speed and duplex via ethtool.
  16  *        Needed for 802.3ad and other future modes.
  17  *
  18  * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
  19  *              Shmulik Hen <shmulik.hen at intel dot com>
  20  *      - Enable support of modes that need to use the unique mac address of
  21  *        each slave.
  22  *
  23  * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
  24  *              Amir Noam <amir.noam at intel dot com>
  25  *      - Moved driver's private data types to bonding.h
  26  *
  27  * 2003/03/18 - Amir Noam <amir.noam at intel dot com>,
  28  *              Tsippy Mendelson <tsippy.mendelson at intel dot com> and
  29  *              Shmulik Hen <shmulik.hen at intel dot com>
  30  *      - Added support for IEEE 802.3ad Dynamic link aggregation mode.
  31  *
  32  * 2003/05/01 - Amir Noam <amir.noam at intel dot com>
  33  *      - Added ABI version control to restore compatibility between
  34  *        new/old ifenslave and new/old bonding.
  35  *
  36  * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
  37  *      - Code cleanup and style changes
