PCIe root complex integrated endpoint does not implement ARI, so this kind of endpoint uses 3-bit function number. The function dependency link of the integrated endpoint should be calculated using the device number plus the value from function dependency link register. Normal endpoint always implements ARI and the function dependency link register contains 8-bit function number (i.e. `devfn' from software's perspective).
