Which conflicts? These macros are there precisely to change
how the header behaves.

Hi Michael
I think including the header files should be placed before the
macro definition.
If VIRTIO_PCI_NO_LEGACY and VIRTIO_RING_NO_LEGACY are needed for
control header file, we should put them at the beginning of
virtio_pci_common.h.
What do you think?

I think you should read the code in question not make guesses.
