46 EFI_SUCCESS - The operation completed successfully.\r
47 EFI_NOT_STARTED - The driver instance has not been started.\r
48 EFI_NO_MAPPING - When using the default address, configuration(DHCP,\r
49 BOOTP, RARP, etc.) is not finished yet.\r
50 EFI_OUT_OF_RESOURCES - Could not add the entry to the routing table.\r
51 EFI_NOT_FOUND - This route is not in the routing table\r
52 (when RouteInfo->DeleteRoute is TRUE).\r
53 EFI_ACCESS_DENIED - The route is already defined in the routing table\r
