> Subject: [PATCH 1/7] MdePkg/IndustryStandard/Pci23: add vendor-specific capability header
>
> Revision 2.2 of the PCI Spec defines Capability IDs 0 through 6,
> inclusive, in Appendix H. It reserves IDs 7 through 255.
>
> Revision 2.3 of the PCI Spec adds Capability IDs 7 through 0xC, inclusive,
> in Appendix H. Capability ID 9 stands for "Vendor Specific".
>
> Add the EFI_PCI_CAPABILITY_ID_VENDOR macro and the
> EFI_PCI_CAPABILITY_VENDOR_HDR structure type to MdePkg/IndustryStandard,
> in order to describe this capability header.
