- * Changes:
- *
- * 2003/05/01 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Amir Noam <amir.noam at intel dot com>
- * - Added support for lacp_rate module param.
- *
- * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Based on discussion on mailing list, changed locking scheme
- * to use lock/unlock or lock_bh/unlock_bh appropriately instead
- * of lock_irqsave/unlock_irqrestore. The new scheme helps exposing
- * hidden bugs and solves system hangs that occurred due to the fact
- * that holding lock_irqsave doesn't prevent softirqs from running.
- * This also increases total throughput since interrupts are not
- * blocked on each transmitted packets or monitor timeout.
- *
- * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Renamed bond_3ad_link_status_changed() to
- * bond_3ad_handle_link_change() for compatibility with TLB.
- *
- * 2003/05/20 - Amir Noam <amir.noam at intel dot com>
- * - Fix long fail over time when releasing last slave of an active
- * aggregator - send LACPDU on unbind of slave to tell partner this
- * port is no longer aggregatable.
- *
- * 2003/06/25 - Tsippy Mendelson <tsippy.mendelson at intel dot com>
- * - Send LACPDU as highest priority packet to further fix the above
- * problem on very high Tx traffic load where packets may get dropped
- * by the slave.
- *
- * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Code cleanup and style changes
