pci.h
[+] struct pci_access (3)

	Change	Effect
1	Field fd_vpd has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
2	The relative position of field cached_dev has been changed from 20 to 21.	Applications will access incorrect memory when attempting to access this field.
3	The relative position of field fd_pos has been changed from 21 to 20.	Applications will access incorrect memory when attempting to access this field.
