NDIS_NET_BUFFER_LIST_FILTERING_INFO structure (ndis.h)

The NDIS_NET_BUFFER_LIST_FILTERING_INFO structure defines filtering information that is associated with a NET_BUFFER_LIST structure.

Syntax

typedef struct _NDIS_NET_BUFFER_LIST_FILTERING_INFO {
  union {
    struct {
      USHORT FilterId;
      union {
        USHORT QueueId;
        USHORT VPortId;
      } QueueVPortInfo;
    } FilteringInfo;
    PVOID Value;
  };
} NDIS_NET_BUFFER_LIST_FILTERING_INFO, *PNDIS_NET_BUFFER_LIST_FILTERING_INFO;

Members

FilteringInfo

A structure that contains the following members:

FilteringInfo.FilterId

A USHORT value that contains a receive filter identifier. The receive filter identifier is an integer from one to the number of receive filters that the network adapter supports.

Note  Starting with NDIS 6.20, this member must be set to zero.

 

FilteringInfo.QueueVPortInfo

A union that contains the following members:

FilteringInfo.QueueVPortInfo.QueueId

A USHORT value that contains an identifier for a virtual machine queue (VMQ) receive queue. The queue identifier is an integer between zero and the number of queues that the network adapter supports. A value of NDIS_DEFAULT_RECEIVE_QUEUE_ID specifies the default receive queue.

Note  Starting with Windows Server 2012, the value of this member must always be set to NDIS_DEFAULT_RECEIVE_QUEUE_ID by miniport drivers that support the SR-IOV interface.

 

FilteringInfo.QueueVPortInfo.VPortId

A USHORT value that contains the identifier for a virtual port (VPort). A value of NDIS_DEFAULT_VPORT_ID specifies the default VPort on the NIC switch.

The VPort with the specified VPortId value must have previously been created through a set request of OID_NIC_SWITCH_CREATE_VPORT.

Note  For the VMQ interface, this member must be set to NDIS_DEFAULT_VPORT_ID.

 

Value

A PVOID type value that is in a union with the FilteringInfo member. This member lets a driver access all the information in the NDIS_NET_BUFFER_LIST_FILTERING_INFO structure as one PVOID value.

Remarks

Starting with NDIS 6.20, miniport drivers use the NDIS_NET_BUFFER_LIST_FILTERING_INFO structure to specify receive filter information that accompanies the NET_BUFFER structures that are associated with a NET_BUFFER_LIST structure.

To access the NDIS_NET_BUFFER_LIST_FILTERING_INFO structure from the NET_BUFFER_LIST OOB data, an NDIS driver calls the NET_BUFFER_LIST_INFO macro and specifies the NetBufferListFilteringInfo information type.

To access the identifier values directly, use the NET_BUFFER_LIST_RECEIVE_FILTER_ID, NET_BUFFER_LIST_RECEIVE_FILTER_VPORT_ID, or NET_BUFFER_LIST_RECEIVE_QUEUE_ID macros.
