 This way a filter expression can match a header field, irrespective of the
 representation of it in the specific protocol context. This is interesting
 for protocols with variable-width header fields.
 
+The HFILL macro at the end of the struct will set resonable default values

 A protocol item is added to an existing protocol tree with one of a
