- * Description:
- *
- * Public header file for the "GEnesis" common module "CSUM".
- *
- * "GEnesis" is an abbreviation of "Gigabit Ethernet Network System in Silicon"
- * and is the code name of this SysKonnect project.
- *
- * Compilation Options:
- *
- * SK_USE_CSUM - Define if CSUM is to be used. Otherwise, CSUM will be an
- * empty module.
- *
- * SKCS_OVERWRITE_PROTO - Define to overwrite the default protocol id
- * definitions. In this case, all SKCS_PROTO_xxx definitions must be made
- * external.
- *
- * SKCS_OVERWRITE_STATUS - Define to overwrite the default return status
- * definitions. In this case, all SKCS_STATUS_xxx definitions must be made
- * external.
- *
- * Include File Hierarchy:
- *
- * "h/skcsum.h"
- * "h/sktypes.h"
