PLDM device identifiers:

The format of data is based on the PLDM QueryDeviceIdentifiers response, but might not be identical to it as this index has a fixed list of descriptors with a fixed ordering.Byte 0: 0x0 (Completion Code)Bytes 1-4: Total length of descriptors in bytes starting at byte 6Byte 5: Total number of descriptorsBytes 6-N: List of device descriptorsThe list of device descriptors includes:

• PCI Vendor ID

• PCI Device ID

• PCI Subsystem Vendor ID

• PCI Sybsystem ID

• If APSKU present on the device: Vendor defined block with content:

  • APSKU

All multi-byte fields are little endian.
