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 |
