I noticed most of the pcie-root-ports get a new value for the port attribute after the change, while the chassis attribute remains always the same AFAICT. That's because the chassis attribute is just set to the index of the controller, while port is set to slot<<3 + function (this was recommended by some PCI person, Alex I think). I believe chassis needs to be unique within the entire machine, while port needs to be unique only for the bus that the controller is connected to.
Again, I don't think this is a problem at all, but it would be nice to get a confirmation the attributes are indeed being used properly. Is their meaning documented anywhere? -- Andrea Bolognani / Red Hat / Virtualization
