The MAC address stuff is workable to tell if it's a r8153-AD (which is in Dell Inc Type C
dongles,  TB16 and WD15 docks).

This alone wouldn't be enough to tell if it's a TB16.  I believe you'd need to have an
extra check for that, but maybe this workaround can run after you verify it's r8153-AD
in the special MAC address handling section of r8153 driver.
