I was pretty sure there was a confirmed kernel bug where driver(s) were
incorrectly padding minimum Ethernet frames by an extra 4 bytes, but I can't
find it now.  If this can be confirmed, then we might even have a quad-state
option - the 3 above and a 4th one "assume the device is running a faulty
driver and log an expert info for the excess 4 bytes".
