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 | |

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> | |
