Bring DOCSIS Mac Management "dissectors" into modernity.
1. Use proto_tree_add_item_ret_uint to remove separate "gets" 2. Remove if (tree)s that prevented expert_info 3. Apply consistent whitespace 4. Apply consistent TLV behavior, making T and L always filterable 5. Remove T name (of TLV) from field name itself (where applicable) 6. Use BASE_UNIT_STRING and BASE_NO_DISPLAY_VALUE Tested with capture generated from https://github.com/AdrianSimionov/docsis-generator Change-Id: I9987397ccb3248b2a26d850af468740f94b28a63 Reviewed-on: https://code.wireshark.org/review/21561 Petri-Dish: Michael Mann <mmann78@netscape.net> Tested-by: Petri Dish Buildbot <buildbot-no-reply@wireshark.org> Reviewed-by: Anders Broman <a.broman58@gmail.com>
