What we would do are: - 1. don't update NumCellsUsed for AF43 packets, otherwise update them - 2. don't update NumTX/NumTxAck for AF43 packets, otherwise update them The first one may cause undesirable deallocations. If a node has relayed join request continuously for a certain period of time, the computed cell utilization (NumCellsUsed / NumCellsElapsed) goes down, then a negotiated TX cell will be deleted, even if the negotiated TX cell was scheduled to handle application traffic to forward. This behavior may degrade end-to-end reliability. The second one may prevent the node from monitoring link PDRs on scheduled cells correctly. This could affect the scheduling collision detection.
