PCI Device Ordering: In Red Hat Enterprise Linux 6, the PCI device ordering is based on the PCI device enumeration. PCI device enumeration is based on the PCI enumeration algorithm (depth first then breadth) and is constant per system type. Additionally, once the devices are discovered, the module loading process is sequentialized, providing persistent naming of the interfaces.
