As a query request, administrative applications (or possibly overlying drivers) can use the OID_TCP_CONNECTION_OFFLOAD_CURRENT_CONFIG OID to determine the currently-enabled connection offload capabilities of an underlying miniport adapter. A system administrator can use this OID through the Microsoft Windows Management Instrumentation (WMI) interface.
NDIS handles this OID for miniport drivers. Miniport drivers report miniport adapter connection offload settings to NDIS. For information about passing connection offload configuration settings to NDIS from a miniport driver and from NDIS to overlying drivers, see NDIS_TCP_CONNECTION_OFFLOAD.
In response to OID_TCP_CONNECTION_OFFLOAD_CURRENT_CONFIG, the Encapsulation member of NDIS_TCP_CONNECTION_OFFLOAD defines the current packet encapsulation configuration of the miniport adapter. NDIS provides a bitwise OR of the flags that are provided in the Encapsulation member. The other members of NDIS_TCP_CONNECTION_OFFLOAD contain settings for various connection offload services. For more information about encapsulation and other capabilities, see NDIS_TCP_CONNECTION_OFFLOAD and NDIS_OFFLOAD_PARAMETERS.
