I don't think they were ever intended for drivers; I think they were supposed to be helper macros for msi.c.

I think you're right. Unfortunately, the old MSI-X ECN was actually incorporated into a version of the PCI 3.0 spec -- I have a document here named pci3.0-081202.pdf which has exactly the layout you describe. So it probably gained wider currency than it should have. > - Remove PCI_MSIX_FLAGS_BITMASK. > This definition also come from the draft ECN.
