The Anker Prime TB5 dock identifies itself in the DROM as 01ea:83b5. Its router config space is an Intel Barlow Ridge 80G hub (8087:5786). The upstream lane adapter advertises CL0s, CL1, and CL2. With CLx left enabled, TMU uni-directional LowRes setup fails with -ENOTCONN, the USB3 and DisplayPort tunnels are aborted, and the router reconnects in a loop. Loading thunderbolt with clx=0 keeps the link up on this machine. Match the DROM id together with the Barlow Ridge hub id and disable CL states for this dock only. QUIRK_NO_CLX takes the same early-out as the module parameter, without disabling CLx for every other router.
