15 | * 2003/03/18 - Amir Noam <amir.noam at intel dot com> | |
16 | * - Added support for getting slave's speed and duplex via ethtool. | |
17 | * Needed for 802.3ad and other future modes. | |
18 | * | |
19 | * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and | |
20 | * Shmulik Hen <shmulik.hen at intel dot com> | |
21 | * - Enable support of modes that need to use the unique mac address of | |
22 | * each slave. | |
23 | * | |
24 | * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and | |
25 | * Amir Noam <amir.noam at intel dot com> | |
26 | * - Moved driver's private data types to bonding.h | |

29 | * Tsippy Mendelson <tsippy.mendelson at intel dot com> and | |
30 | * Shmulik Hen <shmulik.hen at intel dot com> | |
31 | * - Added support for IEEE 802.3ad Dynamic link aggregation mode. | |
32 | * | |
33 | * 2003/05/01 - Amir Noam <amir.noam at intel dot com> | |
34 | * - Added ABI version control to restore compatibility between | |
35 | * new/old ifenslave and new/old bonding. | |
36 | * | |
37 | * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com> | |
38 | * - Code cleanup and style changes | |
39 | * | |
40 | * 2005/05/05 - Jason Gabler <jygabler at lbl dot gov> | |
41 | * - added definitions for various XOR hashing policies | |
