+ * A common theme here is that the driver wants some degree of
+ * control of the type of reset used, vfio specifically wants to specify a
+ * bus or slot reset while hfi1 just wants to specify that the link is
+ * reset and doesn't care if it's a bus or slot reset that accomplishes
+ * that.  The right "unified" interface is one that takes a parameter
+ * allowing the caller to specify the scope or type of reset
+ * with aliases so drivers can ignore the hotplug interface if they wish
+ * for special cases.
+ *
+ * PCI_RESET_ANY tries all reset type one by one until device is successfully
+ * reset. Under normal circumstances, most drivers are expected to use
+ * PCI_RESET_ANY as they don't usually care about the type of reset as long
+ * as device is reset.
+ *
+ * PCI_RESET_FUNC is useful when you want to reset one particular PCI device
+ * but you don't want to impact other devices or cause a temporary service
+ * outage.
+ *
+ * PCI_RESET_LINK can be used to cause a link retraining. This operation will
+ * cause service outage for the PCI bus if there are other devices on the same
+ * bus. PCI_RESET_LINK determines if a platform supports hotplug or not and
+ * suppresses hotplug interrupts during secondary bus reset.
+ *
+ * PCI_RESET_DEV_SPECIFIC can be used to reset a device by help from the
+ * device driver. Not all device drivers support this option.
+ *
+ * PCI_RESET_FLR can be used to issue a Function Level Reset to a device. This
+ * option will fail if FLR is not supported.
+ *
+ * PCI_RESET_PM can be used to reset the device via D3->D0 and D0->D3 sleep
+ * transition. This assumes that device supports PM based reset.
+ *
+ * PCI_RESET_SLOT forces a slot/hotplug reset. This will not work on platforms
+ * without hotplug capability. This option should only be used for advanced
+ * use-cases where driver developer absolutely knows that the device will never
+ * be used on non-hotplug environments.
+ * Not recommended for scalability. Please refer to PCI_RESET_LINK and let the
+ * PCI core do the hotplug detection.
+ *
+ * PCI_RESET_BUS performs a secondary bus reset on the link and causes a link
+ * recovery. Using this option directly and bypassing hotplug driver may
+ * cause a deadlock if platform supports hotplug. Please refer to
+ * PCI_RESET_LINK and let the PCI core do the hotplug detection.
