| 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 |

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