Using NDIS 6.20 Data Structures
NDIS can support multiple versions of the same data structure. NDIS 6.20 and later drivers that use updated structures must report the correct Revision member and Size member value in the NDIS_OBJECT_HEADER structure that is in the Header member of a structure, if any, when the drivers initialize NDIS 6.20 data structures.
Note To determine the correct version and size information see the reference pages for each structure that includes a Header member. The reference pages for structures that contain a Header member and that have been updated for NDIS 6.20 include new information for NDIS 6.20 and later drivers. If there is no update to the structure for NDIS 6.20, the information that is provided for NDIS 6.0 or NDIS 6.1 drivers also applies to NDIS 6.20 and later drivers.
