Version Information Requirements for NDIS
NDIS supports various header version information requirements that guarantee consistent behavior between NDIS versions. To support header version information, NDIS has the following responsibilities:
Handles structures with lower revisions. That is, NDIS checks the header information and interprets the structure based upon the revision information in the header.
Fails a function call and returns an appropriate error code if a driver uses an incorrect structure revision. For example, NDIS fails the function call if an NDIS 6.30 driver uses Xxx_REVISION_1 structures when there is an NDIS 6.30 Xxx_REVISION_2 structure.
