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

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
