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
38  *
39  * 2005/05/05 - Jason Gabler <jygabler at lbl dot gov>
40  * - added definitions for various XOR hashing policies
