Michael Brown 2ae5355321 [pci] Backup and restore standard config space across PCIe FLR The behaviour of PCI devices across a function-level reset seems to be inconsistent in practice: some devices will preserve PCI BARs, some will not. Fix the behaviour of FLR on devices that do not preserve PCI BARs by backing up and restoring PCI configuration space across the reset. Preserve only the standard portion of the configuration space, since there may be registers with unexpected side effects in the remaining non-standardised space.
