-	 * QDIO mode is asynchronous -- cc=2 and busy bit there will take
-	 * the queues down immediately; and not being under VM we have a
-	 * problem on cc=2 and busy bit set right away).
-	 *
-	 * Therefore qdio_siga_output will try for a short time constantly,
-	 * if such a condition occurs. If it doesn't change, it will
-	 * increase the busy_siga_counter and save the timestamp, and
-	 * schedule the queue for later processing (via mark_q, using the
-	 * queue tasklet). __qdio_outbound_processing will check out the
-	 * counter. If non-zero, it will call qdio_kick_outbound_q as often
-	 * as the value of the counter. This will attempt further SIGA
-	 * instructions. For each successful SIGA, the counter is
-	 * decreased, for failing SIGAs the counter remains the same, after
-	 * all.
-	 * After some time of no movement, qdio_kick_outbound_q will
-	 * finally fail and reflect corresponding error codes to call
-	 * the upper layer module and have it take the queues down.
-	 *
-	 * Note that this is a change from the original HiperSockets design
-	 * (saying cc=2 and busy bit means take the queues down), but in
-	 * these days Guest LAN didn't exist... excessive cc=2 with busy bit
-	 * conditions will still take the queues down, but the threshold is
