As a query request, the OID_TCP_OFFLOAD_HARDWARE_CAPABILITIES OID reports the task offload hardware capabilities of a miniport adapter's hardware. User-mode applications (or possibly overlying drivers) can query this OID to determine the task offload hardware capabilities of an underlying miniport adapter. A system administrator can use this OID through the Windows Management Instrumentation (WMI) interface.
NDIS handles this OID for miniport drivers. Miniport drivers report miniport adapter hardware capabilities to NDIS. For information about reporting task offload hardware capabilites to NDIS from a miniport driver and from NDIS to overlying drivers, see NDIS_OFFLOAD.
After determining the miniport adapter's hardware capabilities, the overlying applications or drivers can use the OID_TCP_OFFLOAD_PARAMETERS OID to enable capabilities that are currently reported as not enabled by the OID_TCP_OFFLOAD_CURRENT_CONFIG OID.
