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
Jay Vosburgh169a3e62005-06-26 17:54:11 -040038 *
39 * 2005/05/05 - Jason Gabler <jygabler at lbl dot gov>
40 * - added definitions for various XOR hashing policies
