These are intended to be used in virtualization, where assigning a guest address wouldn't be translated in the assignment to root port and child devices because the addresses exist within the assignment message. These values will only reflect the membars when enabled in the BIOS, as determined by a register in the VMD device. This patch declares this option as a bit in the pci id driver_data, so that future conforming device ids can be enabled through sysfs new_id if necessary.
