Querying Packet Coalescing Capabilities

Once the miniport driver is initialized, overlying drivers and applications can issue the following OID query requests to obtain the packet coalescing capabilities of the network adapter:

• OID_RECEIVE_FILTER_HARDWARE_CAPABILITIES

• OID_RECEIVE_FILTER_CURRENT_CAPABILITIES

• OID_RECEIVE_FILTER_GLOBAL_PARAMETERS

NDIS handles these OID query requests for miniport drivers and returns the packet coalescing capabilities that the miniport driver registered when NDIS called the driver's MiniportInitializeEx function. Therefore, these OID query requests are not handled by miniport drivers.

For more information about how the miniport driver registers its packet coalescing capabilities, see Determining Receive Filtering Capabilities.
