Name	Type	Description
NrRlcUmTxEntity	simple module	NR (TS 38.322) transmission side of the Unacknowledged Mode (UM) of the RLC layer: SI + byte-offset (SO) segmentation, one SDU segment per PDU, one sequence number per SDU. Shares the common RlcUmTxEntityBase shell (MAC plumbing, D2D mode-switch machinery) with the LTE profile LteRlcUmTxEntity. Bound by default inside the NrRlcUmEntity compound. The NR SO-segmentation statistics are declared here so they are recorded only for NR entities.
