As a query request, the OID_TCP_CONNECTION_OFFLOAD_HARDWARE_CAPABILITIES OID reports the current connection offload hardware capabilities of an underlying miniport adapter. User-mode applications (or possibly overlying drivers) can query this OID to determine the connection offload hardware capabilities of an underlying miniport adapter. A system administrator can use this OID through the Microsoft Windows Management Instrumentation (WMI) interface.
Set requests are not supported.
NDIS handles this OID for miniport drivers. Miniport drivers report miniport adapter connection offload hardware capabilities to NDIS. For information about passing connection offload hardware capabilities to NDIS from a miniport driver and from NDIS to overlying drivers, see NDIS_TCP_CONNECTION_OFFLOAD.
In response to OID_TCP_CONNECTION_OFFLOAD_HARDWARE_CAPABILITIES, the Encapsulation member of NDIS_TCP_CONNECTION_OFFLOAD defines the current packet encapsulation hardware capabilities 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.
