Thanks. This is a good example of how to chain protocol dissectors, but 
this doesn't solve my problem.

It's similar to the following: I have to dissect some IP fields only if 
the higher layer protocol is TCP, and dissection code for these fields 
is TCP specific. If I have UDP instead of TCP, the dissection code for 
the same fields is different. And I don't have ip.proto field :-(
