## PDCP Rx flow
At the Rx side, `pdcp_data_ind()` serves as the entry point for receiving data from RLC. Within `pdcp_data_ind()`, the PDCP manager mutex protects access to the PDU receiving function of PDCP (`recv_pdu()` callback corresponding to `nr_pdcp_entity_recv_pdu()` for DRBs). Following this, the `deliver_sdu_drb()` function dispatches the received data to the GTP thread via an ITTI message (`GTPV1U_TUNNEL_DATA_REQ`).
