Routine Description:

    Entry point called by NDIS to query for the value of the specified OID.
    Typical processing is to forward the query down to the underlying miniport.

    The following OIDs are filtered here:

    OID_PNP_QUERY_POWER - return success right here

    OID_GEN_SUPPORTED_GUIDS - do not forward, otherwise we will show up
    multiple instances of private GUIDs supported by the underlying miniport.

    OID_PNP_CAPABILITIES - we do send this down to the lower miniport, but
    the values returned are postprocessed before we complete this request;
    see PtRequestComplete.

    NOTE on OID_TCP_TASK_OFFLOAD - if this IM driver modifies the contents
    of data it passes through such that a lower miniport may not be able
    to perform TCP task offload, then it should not forward this OID down,
    but fail it here with the status NDIS_STATUS_NOT_SUPPORTED. This is to
    avoid performing incorrect transformations on data.

    If our miniport edge (upper edge) is at a low-power state, fail the request.

    If our protocol edge (lower edge) has been notified of a low-power state,
    we pend this request until the miniport below has been set to D0. Since
    requests to miniports are serialized always, at most a single request will
    be pended.

Arguments:

    MiniportAdapterContext    Pointer to the adapter structure
    Oid                       Oid for this query
    InformationBuffer         Buffer for information
    InformationBufferLength   Size of this buffer
    BytesWritten              Specifies how much info is written
    BytesNeeded               In case the buffer is smaller than what we need, tell them how much is needed


Return Value:

    Return code from the NdisRequest below.
