Add support to start or stop a particular queue that is associated with the adapter. Start function enables the Tx adapter to start enqueueing packets to the Tx queue. Stop function stops the Tx adapter from enqueueing any packets to the Tx queue. The stop API also frees any packets that may have been buffered for this queue. All in-flight packets destined to the queue are freed by the adapter runtime until the queue is started again.
