| 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. |

| A count value that indicates the number of times 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. |
