Hi,

It seems good (to me) with however some comments :
  - some core developers (and compilers) are pretty unhappy to see
commas after the last element in the initialization of an array,
  - the same for declarations after statement,
  - try to avoid 'if (tree)' if it has already been tested before!
(probably a symptom telling that it's time to split the concerned function.)
  - finally, don't forget to remove any compiler warning. The wireshark
community has made some substantial efforts these last days to get rid
of the majority of warnings. Please do the same within your code. thanks
:)  (There is only one, that's not too much :) )


Others details :
- Is there a section for this protocol on the wiki?
- Have you a capture trace that you can share on the capture trace wiki
page?
- Have you fuzz-tested your dissector?


P.S. : next time, please provide a *patch* ;)
svn add epan/dissectors/packet-drda.c
svn diff | gzip > packet-drda.diff.gz
It will also include the modifications made in the Makefile.common


Regards,
Sebastien Tandel
