c413cdd by Guy Harris (guy@xxxxxxxxxxxx):

    Comments on the first nibble stuff.
    
    If you don't have control words - and several MPLS pseudo-wire RFCs say
    "in these cases, a control word isn't necessary, and isn't useful, so
    you might want to leave it out" - the first nibble values of 0, 1, 4,
    and 6 could just be part of the packet header.
    
    Explain some other stuff as well.
