From: Ursula Braun If the set_mac_address() function of qeth is invoked, qeth deletes the old mac address first on OSA. Only if deletion returns successfully the new mac address is set on OSA. Deletion may return with a return value "MAC not found on OSA". In this case qeth should continue setting the new mac address. When the OSA cable is pulled, OSA forgets any set mac address. If the OSA network interface acts as a slave to a bonding master interface, bonding can invoke the set_mac_address function for failover purposes and depends on successful setting of the new mac address even though the old mac address could no longer be deleted.
