| * This message is sent from an application to specify if the kernel should |
| * allow unlabled packets to pass if they do not match any of the static |
| * mappings defined in the unlabeled module. |
| * |
| * Required attributes: |
| * |
| * NLBL_UNLABEL_A_ACPTFLG |
| * |
| * o LIST |
| * This message can be sent either from an application or by the kernel in |
| * response to an application generated LIST message. When sent by an |
| * application there is no payload. The kernel should respond to a LIST |
| * message with a LIST message on success. |
