--
dissector_try_unit() is called on the avb_dissector_table after the mr, gv and
tv fields have been dissected, but those fields are not common to all 1722
protocols.  As the comment in the current code indicates, the common portion of
the 1722 PDU ends after the version item.

Also, the subdissectors should be called outside the if(tree) condition in
order to give the subdissector the opportunity to display items in the info
and/or protocol fields in the GUI.
