Like all other "odd" USB devices are currently handled? It is not the device which is odd, but rather the environment in which it is being used for this specific case. I'd expect to see the same SMSC9514 chip also used in off-the-shelf USB-to-Ethernet dongles with no quirks needed. However, a different part of the kernel knows already perfectly well when it is actually running on that specific board. Hence the desire to come up with a mechanism allowing to tell the driver about a quirk for the particular device instance on this board without having to do the heavy round trip through user space.
