TSE and EtherType = 0..45

There is one behaviour that is not described in TSE datasheets: the TSE will not properly forward an incoming ethernet frame to user application in case the frame type is in range 0 ... 45 (decimal). In this case, regradless the actual size of ethernet frame only the amount specified in frame type + 14 bytes are passed to user application, rest is cut. 

But, when the frame type is > 45 the full frame, regardless of actual size, is passed to user. 

This is a problem for some applications where the ether_type could be anything (random) and not linked to the actual size of frame.
