SDAP reconfiguration according to 37.324

SDAP entity is responsible for mapping between DRBs and QoS Flows. If DRB is already configured, e.g. UE receives an RRC Reconfiguration message , if sdap-Config is included in the radioBearerConfig->drb_ToAddModList, reconfigure the SDAP entity in accordance with the received sdap-Config:

• for each mappedQoS-FlowsToAdd item: update QFI to DRB mapping accordingly
• for each mappedQoS-FlowsToRelease item: update QFI to DRB mapping accordingly

Possible extra task:

• Rework SDAP call from RRC instead of PDCP: nr_reconfigure_sdap_entity can be called independently from nr_pdcp_reconfigure_drb
