tSapIngressQueueExpedite specifies the priority that this queue should be assigned by the hardware level schedulers. The value 'auto-expedited' implies that this attribute should be dynamically updated by looking at the forwarding classes mapping into this queue. In such a case the queue is treated as 'non-expedited' if there is even a single non-expedited forwarding class using this queue. This attribute is associated with the queue at the time of creation and cannot be modified thereafter.
