[erlang-questions] Packets deduplication

[Danil Zagoskin]

Hi!

If ID grows monotinically and you have no plans of recovering after packet
reordering, then you can just keep the previous ID.
  - If CurID > PrevID, CurID is unique;
  - If CurID == PrevID, it is not unique;
  - If CurID < PrevID, it is a bug or reordering, let it crash.
