I consistently had similar problems with my 0x17ef/0x3066 "ThinkPad
Thunderbolt 3 Dock MCU", but they went away after I forced it to
use the if_cdce driver instead with this quirk:

        /* This works much better with if_cdce than if_ure */
        USB_QUIRK(LENOVO, TBT3LAN,  0x0000, 0xffff, UQ_CFG_INDEX_1),
