PCIe* Device Security Enhancements Specification.

|
NOTE: The data structure is not fully match the current specification,
|
because it is aligned with the real hardware implementation with minor adjustment
|
on INTEL_PCI_DIGEST_CAPABILITY_STRUCTURE, INTEL_PCI_DIGEST_DATA_MODIFIED and
|
INTEL_PCI_DIGEST_DATA_VALID.
