Sparc64 also uses packets ("mondos", not implemented yet) for
interrupt vector data, there the packet size is 8 * 64 bits. I think
we should aim for a more generic API that covers this case also.
For example, irq.c could support opaque packet payload of
unspecified/predefined size. MSI packet structure should be defined in
ioapic.c.
The pci_msi_ops structure could be 'const', or do you expect it to
change during execution?
