320 			 of entries into the Ring has looped around the ring.

322 			 loop, this value is set to 1. After the max value is reached
323 			 allowed by the number of bits for this field, the count
324 			 value continues with 0 again.

328 			 has created new entries. This eliminates the need to check
329 			 where the "head pointer' of the ring is located once the
330 			 SW starts processing an interrupt indicating that new entries
331 			 have been put into this ring...

334 			LSB bit of this count value.
