Hi Pascal,
  I went through the latest rev and found an off-by-one error on the Fragment 
size.

* Section 5.1.

   Fragment_Size:  10-bit unsigned integer; the size of this fragment in
      a unit that depends on the Link-Layer technology.  Unless
      overridden by a more specific specification, that unit is the
      byte, which allows fragments up to 1024 bytes.

Shouldn’t this be fragments upto *1023* bytes instead of 1024 bytes?

Thanks
Suresh
