Hi,

Could someone help explain why writing to "rescan" under "/sys/bus/pci/devices/.../rescan" will force a rescan of the device's parent bus instead of just re-discover all the devices behind this device (if the device is type-0, then nothing happens).

Is there any user space interface that could let user just rescan devices behind one specified type-1 device?

Thanks,
Aaron
