This doesn't seem to make sense. is_thunderbolt indicates that a device is part of a Thunderbolt controller. See the code comment: > - unsigned int is_thunderbolt:1; /* Thunderbolt controller */ A Thunderbolt controller is not necessarily tunneled. The PCIe switch, NHI and XHCI of the Thunderbolt host controller are not tunneled at all. Thanks, Lukas
