Andre Puschmann 091877fd2a gnb,rrc: inverse order of configuring lower layers when establishing bearer 
start with lower layers first, so MAC, RLC then PDCP.
Since PDCP requires that the LCID is already registered at RLC to make config
checks. It checks for RLC mode (UM) in this case causing log entries like:

2021-12-01T13:47:40.453641 [RLC-NR ] [W] LCID 4 doesn't exist.

Pedro Alvarez 1bea5a7ebe gnb,rrc_nr: make sure that we only push the NAS PDU on the SMC if it exists. 3 years ago
Pedro Alvarez f9a2850d74 gnb,ngap: Added interface so the NGAP can pass a NAS message to the RRC 
upon starting the RRC Security Mode command. This allows the gNB to
pass this message only after the SM procedure is complete.

Also made sure that the RRC notifies the NGAP upon the end of the
reconfiguration procedure, to make sure that the NGAP sends the UE
context setup response.
