/*
 * The following NetLabel payloads are supported by the CIPSO subsystem.
 *
 * o ADD:
 *   Sent by an application to add a new DOI mapping table.
 *
 *   Required attributes:
 *
 *     NLBL_CIPSOV4_A_DOI
 *     NLBL_CIPSOV4_A_MTYPE
 *     NLBL_CIPSOV4_A_TAGLST
 *
 *   If using CIPSO_V4_MAP_TRANS the following attributes are required:
 *
 *     NLBL_CIPSOV4_A_MLSLVLLST
 *     NLBL_CIPSOV4_A_MLSCATLST
 *
 *   If using CIPSO_V4_MAP_PASS or CIPSO_V4_MAP_LOCAL no additional attributes
 *   are required.
 *
 * o REMOVE:
 *   Sent by an application to remove a specific DOI mapping table from the
 *   CIPSO V4 system.
 *
 *   Required attributes:
 *
 *     NLBL_CIPSOV4_A_DOI
 *
 * o LIST:
 *   Sent by an application to list the details of a DOI definition.  On
 *   success the kernel should send a response using the following format.
 *
 *   Required attributes:
 *
 *     NLBL_CIPSOV4_A_DOI
 *
 *   The valid response message format depends on the type of the DOI mapping,
 *   the defined formats are shown below.
 *
 *   Required attributes:
 *
 *     NLBL_CIPSOV4_A_MTYPE
 *     NLBL_CIPSOV4_A_TAGLST
 *
 *   If using CIPSO_V4_MAP_TRANS the following attributes are required:

 *     NLBL_CIPSOV4_A_MLSLVLLST
 *     NLBL_CIPSOV4_A_MLSCATLST
 *
 *   If using CIPSO_V4_MAP_PASS or CIPSO_V4_MAP_LOCAL no additional attributes
 *   are required.
 *
 * o LISTALL:
 *   This message is sent by an application to list the valid DOIs on the
 *   system.  When sent by an application there is no payload and the
 *   NLM_F_DUMP flag should be set.  The kernel should respond with a series of
 *   the following messages.
 *
 *   Required attributes:
 *
 *    NLBL_CIPSOV4_A_DOI
 *    NLBL_CIPSOV4_A_MTYPE
