DESCRIPTION

16       A PCI bus may host multiple slots, each slot may support a reset
17       mechanism independent of other slots. For instance, some slots may
18       support slot power control. In the case of a 1:1 bus to slot
19       architecture, this function may wrap the bus reset to avoid spurious
20       slot related events such as hotplug. Generally a slot reset should be
21       attempted before a bus reset. All of the function of the slot and any
22       subordinate buses behind the slot are reset through this function. PCI
23       config space of all devices in the slot and behind the slot is saved
24       before and restored after reset.
