+ * The following NetLabel payloads are supported by the management interface.
+ *
+ * o ADD:
+ * Sent by an application to add a domain mapping to the NetLabel system.
+ *
+ * Required attributes:
+ *
+ * NLBL_MGMT_A_DOMAIN
+ * NLBL_MGMT_A_PROTOCOL
+ *
+ * If IPv4 is specified the following attributes are required:
+ *
+ * NLBL_MGMT_A_IPV4ADDR
+ * NLBL_MGMT_A_IPV4MASK
+ *
+ * If IPv6 is specified the following attributes are required:
+ *
+ * NLBL_MGMT_A_IPV6ADDR
+ * NLBL_MGMT_A_IPV6MASK
+ *
+ * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
+ *
+ * NLBL_MGMT_A_CV4DOI
+ *
+ * If using NETLBL_NLTYPE_UNLABELED no other attributes are required,
+ * however the following attribute may optionally be sent:
+ *
+ * NLBL_MGMT_A_FAMILY
+ *
+ * o REMOVE:
+ * Sent by an application to remove a domain mapping from the NetLabel
+ * system.
+ *
+ * Required attributes:
+ *
+ * NLBL_MGMT_A_DOMAIN
+ *
+ * o LISTALL:
+ * This message can be sent either from an application or by the kernel in
+ * response to an application generated LISTALL message. 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_MGMT_A_DOMAIN
+ * NLBL_MGMT_A_FAMILY
+ *
+ * If the IP address selectors are not used the following attribute is
+ * required:
+ *
+ * NLBL_MGMT_A_PROTOCOL
+ *
+ * If the IP address selectors are used then the following attritbute is
+ * required:
+ *
+ * NLBL_MGMT_A_SELECTORLIST
+ *
+ * If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
+ * attributes are required:
+ *
+ * NLBL_MGMT_A_CV4DOI
+ *
+ * If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
+ * attributes are required.
+ *
+ * o ADDDEF:
+ * Sent by an application to set the default domain mapping for the NetLabel
+ * system.
+ *
+ * Required attributes:
+ *
+ * NLBL_MGMT_A_PROTOCOL
+ *
+ * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
+ *
+ * NLBL_MGMT_A_CV4DOI
+ *
+ * If using NETLBL_NLTYPE_UNLABELED no other attributes are required,
+ * however the following attribute may optionally be sent:
+ *
+ * NLBL_MGMT_A_FAMILY
+ *
+ * o REMOVEDEF:
+ * Sent by an application to remove the default domain mapping from the
+ * NetLabel system, there is no payload.
+ *
+ * o LISTDEF:
+ * This message can be sent either from an application or by the kernel in
+ * response to an application generated LISTDEF message. When sent by an
+ * application there may be an optional payload.
+ *
+ * NLBL_MGMT_A_FAMILY
+ *
+ * On success the kernel should send a response using the following format:
+ *
+ * If the IP address selectors are not used the following attributes are
+ * required:
+ *
+ * NLBL_MGMT_A_PROTOCOL
+ * NLBL_MGMT_A_FAMILY
+ *
+ * If the IP address selectors are used then the following attritbute is
+ * required:
+ *
+ * NLBL_MGMT_A_SELECTORLIST
+ *
+ * If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
+ * attributes are required:
+ *
+ * NLBL_MGMT_A_CV4DOI
+ *
+ * If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
+ * attributes are required.
+ *
+ * o PROTOCOLS:
+ * Sent by an application to request a list of configured NetLabel protocols
+ * in the kernel. 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_MGMT_A_PROTOCOL
+ *
+ * o VERSION:
+ * Sent by an application to request the NetLabel version. When sent by an
+ * application there is no payload. This message type is also used by the
+ * kernel to respond to an VERSION request.
+ *
+ * Required attributes:
+ *
+ * NLBL_MGMT_A_VERSION
