/* Description		LOOPING_COUNT

			Consumer: SW/REO/DEBUG

			For debugging.

			A count value that indicates the number of times the producer
			 of entries into this Ring has looped around the ring.
			At initialization time, this value is set to 0. On the first
			 loop, this value is set to 1. After the max value is reached
			 allowed by the number of bits for this field, the count
			 value continues with 0 again.
			
			In case SW is the consumer of the ring entries, it can use
			 this field to figure out up to where the producer of entries
			 has created new entries. This eliminates the need to check
			 where the "head pointer' of the ring is located once the
			 SW starts processing an interrupt indicating that new entries
			 have been put into this ring...
			
			Also note that SW if it wants only needs to look at the 
			LSB bit of this count value.
