> CXL Reset can be exposed as a PCI function reset method only when the
> reset is function-scoped. PCI reset-method probing runs during
> enumeration, so walking sibling functions there can race with functions

>
> Reject multifunction devices for now instead of trying to infer reset
> scope from sibling state. Systems that can prove a multifunction device
> has function-scoped CXL Reset can be enabled later.
