There may be a need to transmit an /E/ code in a frame
by transmit MAC and receive this frame as is by the 
receive MAC. Upon detection of /E/ in D state 
if you go to E state and then Z state then you are trashing the
frame. Which may not be desirable (in this case).

I would suggest encode /E/ and go back to D state and 
process the frame normally.
