Description: The control of the current zoning policy configuration. The procedure for zoning policy configuration is as follows: - user reads nlActiveZoneTable AND/OR nlActiveZoneMemberTable to determine current zone configuration and makes any local edits. - user continually reads back nlZoningPolicyStatus until 'no_current_owner' is received. - user writes its address to nlZoningPolicyControlOwner in order to lock zoning control and then continually reads back nlZoningPolicyStatus until 'request_valid' is received. - user can validate that it has successfully locked zone policy control by reading back its own address from nlZoningPolicyControlOwner. - user (optionally) writes timeout value to nlZoningPolicyTimeout, and then continually reads back nlZoningPolicyStatus until 'request_valid' is received. - user writes 'clear-zoning-configuration' to nlZoningPolicyControl to clear existing ta nlZoningPolicyControl to clear existing table and then continually reads back nlZoningPolicyStatus until 'request_valid' is received. - user continually adds zone OR zone member entries by writing to the appropriate objects using index 0 of the table, and then continually reads back nlZoningPolicyStatus until 'request_valid' is received. - after the last entry is made, user writes 'create_table' to nlZoningPolicyControl, and then continually reads back nlZoningPolicyStatus until 'request_valid' is received. - OR the user writes 'default-zoning-configuration' to load the default zoning configuration and then continually reads back nlZoningPolicyStatus until 'request_valid' is received. - user writes 'clear_owner' to nlZoningPolicyControl (or waits for the zoning timeout to occur) to release ownership of zoning policy configuration.
