when you register a protocol,you should do the following three steps,
1.proto_register_protocol();
2.proto_register_field_array();
3.proto_register_subtree_array()
what does the third function proto_register_subtree_array do?why ?and do
it for what reason?
Essentially: proto_register_subtree() registers variables (usually named
ett_...) which are used to store state as to whether a particular
sub-tree is expanded or not in the "packet-details" pane in the GUI.
See proto_item_add_subtree(...) in the code for pretty much any dissector.
