I happened to notice that this dissector had 2 duplicate display filter fields.
 That's only because there are only 2 fields!  It will be nearly impossible to
find duplicates in other dissectors with large numbers of fields.  Some
automated method should be instituted if possible.
Hmm, perhaps the tools/checkhf.pl script can be enhanced?
In some cases, having two fields with the same name is deliberate - for 
instance, in an IAX2 packet, the timestamp can be a field of either 32 
bits, 16 bits, or 15 bits, depending on the type of packet. In general 
you wan these to be different hf_* definitions, but for the user to be 
able to refer to them with one name.
I'm not sure I'm dead set on this being a feature, but I do think it 
should be thought through before disabling this.
Cheers
