faluco 9058ee9a5b Move gNB metrics processing to the stack thread avoiding concurrency issues in MAC and RRC. 2021-10-06 11:31:54 +02:00
faluco a703279975 Fix a data race when passing the nr_workers to the txrx worker. 
There was an unprotected access of the txrx reading this variable while being set from a different thread.
Fix it by starting the txrx thread after all variables are ready.

Andre Puschmann 06fbb58d70 gnb,mac: add dedicated arguments struct for MAC-NR 
as the PCAP object is now only visible inside MAC-NR we can't
share the PCAP file between EUTRA/NR (like we do in the UE).

This patch removes the hard-coded filename for the NR PCAP file.
