Hmm, that's the funny thing. There is no SNA traffic in there...
  
Which leads me to think I made a typo somewhere. Dunno why the code
ends up in the SNA code, but ok. The ETT_* constants used to create a
subtree, to what level should these be uniquely used?

Example:

ti = proto_item_add_text( tree, ... );
subtree = proto_item_add_subtree(ti, ETT_SUBS);

ti2 = proto_item_add_text ( subtree, ... );
subsubtree = proto_item_add_subtree(ti2, ETT_SUBS);

should this work, or is this blatently stupid?

Can I use a certain ETT_* constant at any place if I feel like it? Or
am I missing something?
