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

| * - Added support for IEEE 802.3ad Dynamic link aggregation mode. |
| * |
| * 2003/05/01 - Amir Noam <amir.noam at intel dot com> |
| * - Added ABI version control to restore compatibility between |
| * new/old ifenslave and new/old bonding. |
| * |
| * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com> |
| * - Code cleanup and style changes |
