Yes, I know :)
but I am not talking abotu MSI/MSI-X, I am talking about the following:
> > >   PCI-X device: PCI-X command register
> > >   PCI-X bridge: upstream and downstream split transaction registers
> > >   PCI Express : PCI Express device control and link control registers

these register values include maxumum MTU for PCI express and other vital
data.
