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