Pedro Alvarez 3e61448a41 gnb,ngap: added logging for Rx NGAP messages. 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.

Carlo Galiotto aa979708a0 rrc-nr,test: add fnc to trigger send_security_cmd 
The SecurityModeCommand procedure was previously initiated by the
RRCSetupComplete msg. However, it should be trigger by the NGAP
through the InitialContextSetupRequest msg.
This commit implements this change and fills in the function of
the NGAP interface that starts the SecurityModeCommand procedure
