0x10 and 0x20 are programing interfaces for I/O APIC and I/O xAPIC
respectively. #define for these values looks good. But I don't know
if I can put new #defines into pci_ids.h and how to name them because
I could not find the header file (including pci_ids.h) that #defines
the values for programming interfaces. So I want to add the comments
to explain these values (0x10, 0x20) instead of adding new #defines into
pci_ids.h for now.
Thanks,
