Mirrors Linux 7.1's pci_ers_result (include/linux/pci.h:920-938): None/CanRecover/NeedReset/Disconnect/Recovered/NoAerDriver. This is the vocabulary Driver::error_detected will return when the AER recovery flow is wired to bound drivers. Currently the legacy RecoveryAction enum (Handled/ResetDevice/RescanBus/Fatal) coexists for the existing on_error callback — PciErsResult is the richer model that will replace it once the driver-manager → driver IPC channel exists for AER dispatch.
