According to the PCIe specification, bit 7:4 of PCI Express Capabilities Register in a PCI Express Capability Structure is used to identify the Device/Port type. If this field equals to 0x7, this PCIe device is a PCI Express to PCI/PCI-X Bridge. While the comment of this value in the code does not comply with the specification. This patch changes the comment to "PCIE to PCI/PCI-X Bridge" instead of "PCI/PCI-X Bridge", which comply with the specification.
