+ * 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

+ * 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
