| hlos_tid_overwrite |
| |
| When set, TCL shall ignore the IP DSCP and VLAN PCP |

| flow search. The field is valid when 'search_type' is 1 or |
| 2. |
| |
| <legal all> |
| |
| cache_set_num |
| |
| Cache set number that should be used to cache the index |
| based search results, for address and flow search. This |
| value should be equal to LSB four bits of the hash value of |
| match data, in case of search index points to an entry which |
| may be used in content based search also. The value can be |
| anything when the entry pointed by search index will not be |

| |
| |
| |
| Helps with debugging when dumping ring contents. |

| <legal all> |
| |
| looping_count |
| |
| A count value that indicates the number of times the |
| producer of entries into the 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. |
