The NDIS_SRIOV_READ_VF_CONFIG_SPACE_PARAMETERS structure specifies the parameters for a read operation on the PCI Express (PCIe) configuration space of a network adapter's Virtual Function (VF).
HeaderThe type, revision, and size of the NDIS_SRIOV_READ_VF_CONFIG_SPACE_PARAMETERS structure. This member is formatted as an NDIS_OBJECT_HEADER structure.
The miniport driver must set the Type member of Header to NDIS_OBJECT_TYPE_DEFAULT. To specify the version of the NDIS_SRIOV_READ_VF_CONFIG_SPACE_PARAMETERS structure, the driver must set the Revision member of Header to the following value:
Original version for NDIS 6.30 and later.
Set the Size member to NDIS_SIZEOF_SRIOV_READ_VF_CONFIG_SPACE_PARAMETERS_REVISION_1.
VFIdAn NDIS_SRIOV_FUNCTION_ID value that specifies the unique identifier of the VF on the network adapter.
Note The VF with the specified NDIS_SRIOV_FUNCTION_ID value must have resources that were previously allocated through an OID set request of OID_NIC_SWITCH_ALLOCATE_VF.
OffsetA ULONG value that specifies the offset within the PCI configuration space of the VF in which data will be read.
LengthA ULONG value that specifies the length, in units of bytes, of the read operation.
BufferOffsetA ULONG value that specifies the offset, in units of bytes, from the beginning of this structure to a buffer that contains the data that is read from the PCI configuration space of the VF.
The NDIS_SRIOV_READ_VF_CONFIG_SPACE_PARAMETERS structure is used in OID method requests of OID_SRIOV_READ_VF_CONFIG_SPACE.
