## Description

This is the NVMe class-specific DEVICE\_SPECIFIC\_INFO payload that a PCIe Function returns in response to a PCIe TDISP GET\_DEVICE\_INTERFACE\_REPORT request (refer to the NVM Express over PCIe Transport Specification). There is no NVMe Admin, I/O, or MI command that transfers this structure -- it is produced by the device's Device Security Module and consumed by a platform TEE Security Module entirely via the PCIe TDISP protocol, outside of any NVMe command/response mechanism. This type is provided purely so that software which has otherwise obtained a DEVICE\_INTERFACE\_REPORT (e.g., from a TDISP/SPDM stack) can decode its NVMe-specific portion.
