RTE flow items & actions use positive values in item & action type. Negative values are reserved for PMD private types. PMD items & actions usually are not exposed to application and are not used to create RTE flows. The patch allows applications with access to PMD flow items & actions ability to integrate RTE and PMD items & actions and use them to create flow rule. RTE flow item or action conversion library accepts positive known element types with predefined sizes only. Private PMD items and actions do not fit into this scheme because PMD type values are negative, each PMD has it's own types numeration and element types and their sizes are not visible at RTE level. To resolve these limitations the patch proposes this solution: 1. PMD can expose elements of pointer size only. RTE flow conversion functions will use pointer size for each configuration object in private PMD element it processes; 2. RTE flow verification will not reject elements with negative type.
