From 8844f15d33c720323227ce61b518aed4549f19d0 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Thu, 21 Sep 2017 10:48:53 +0200 Subject: [PATCH] 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.
