* The FWT algorithm maintain the first level entries available first for a fast look up
* In scenarios where there is a need to delete a first level entry with following index at the
* second level, there is a need to copy the second level entry over the first one, then delete
* the second level entry. The FWT interface register the overwrite call back so we can mirror the
* same entries indexers in both tables
* @param cbk_func: call back function to overwrite the index table entries
