Setting Information for a Connection-Oriented Miniport Driver
To set an OID that a connection-oriented miniport driver maintains, a bound protocol calls NdisCoOidRequest and passes an NDIS_OID_REQUEST structure that specifies the object (OID) that is being queried and that points to a buffer that contains the value to which the object should be set. The call to NdisCoOidRequest causes NDIS to call the miniport driver's MiniportCoOidRequest function, which sets the object with the supplied value.
The call to NdisCoOidRequest can complete synchronously or asynchronously. To complete the call asynchronously, a miniport driver calls NdisCoOidRequestComplete. The following diagram illustrates setting information in a connection-oriented miniport driver.
