The NDIS_SWITCH_PORT_PROPERTY_CUSTOM structure specifies a custom policy property for a Hyper-V extensible switch port.
Independent software vendors (ISVs) define the format for the custom properties. The format of the custom property is proprietary to the ISV.
HeaderThe type, revision, and size of the NDIS_SWITCH_PORT_PROPERTY_CUSTOM structure. This member is formatted as an NDIS_OBJECT_HEADER structure.
The Type member of Header must be set to NDIS_OBJECT_TYPE_DEFAULT. To specify the version of the NDIS_SWITCH_PORT_PROPERTY_CUSTOM structure, the Revision member of Header must be set to the following value:
Original version for NDIS 6.30 and later.
Set the Size member to NDIS_SIZEOF_NDIS_SWITCH_PORT_PROPERTY_CUSTOM_REVISION_1.
FlagsA ULONG value that contains a bitwise OR of flags. This member is reserved for NDIS.
PropertyBufferLengthA ULONG value that specifies the size, in bytes, of the buffer that contains the custom port property.
PropertyBufferOffsetA ULONG value that specifies the offset, in bytes, to the property buffer. The offset is measured from the start of the NDIS_SWITCH_PORT_PROPERTY_CUSTOM structure up to the beginning of the property buffer.
The NDIS_SWITCH_PORT_PROPERTY_CUSTOM structure is used in the following OID set requests:
The NDIS_SWITCH_PORT_PROPERTY_CUSTOM structure follows the NDIS_SWITCH_PORT_PROPERTY_PARAMETERS structure in the buffer that is associated with these OID set requests. The InformationBuffer member of the NDIS_OID_REQUEST structure contains a pointer to this buffer.
Extensible switch extensions can access the custom port property buffer inside an NDIS_SWITCH_PORT_PROPERTY_CUSTOM structure by using the NDIS_SWITCH_PORT_PROPERTY_CUSTOM_GET_BUFFER macro.
