The NDIS_SRIOV_WRITE_VF_CONFIG_SPACE_PARAMETERS structure specifies the parameters for a write 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_WRITE_VF_CONFIG_SPACE_PARAMETERS structure. This member is formatted as an NDIS_OBJECT_HEADER structure.
The driver must set the Type member of Header to NDIS_OBJECT_TYPE_DEFAULT. To specify the version of the NDIS_SRIOV_WRITE_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_WRITE_VF_CONFIG_BLOCK_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 written.
LengthA ULONG value that specifies the length, in units of bytes, of the write 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 to be written to the PCI configuration space of the VF.
The NDIS_SRIOV_WRITE_VF_CONFIG_SPACE_PARAMETERS structure is used in an OID set request of OID_SRIOV_WRITE_VF_CONFIG_SPACE.
