The SSB nFAPI message is only sent every 8 frames, and automatically
repeated by the PHY layer in between. This commit sets the vrb_map
structure in those frames in between nFAPI so that the scheduler does
not schedule on such resources.

The phytest preprocessor schedules only one UE, as many RBs as possible
(largest continuous RB region), with a fixed MCS and time domain
allocation.

MR938 CI: Parse UE TUN interface correctly in S1 mode
- The TUN interface configuration is changed to use program "ip" only. 
- The CI script parsing is changed accordingly: the pipeline will recognize the attempt to bring up the interface of the first UE.

Above commit changed the TUN interface configuration to use program "ip"
only. This commit changes the CI script parsing correspondingly: the
pipeline will recognize the attempt to bring up the interface of the
first UE.

MR921 : Hotfix for DL DCI issue in UE  
Fixing a bug from last MR.  
Fix in nr_dlsim that prevents reporting false 'PDSCH ok' message

MR915 : Fix to avoid RRC->X2AP ticking every msec when x2ap task is not enabled  
The aim of itti RRC_SUBFRAME_PROCESS message (MAC->RRC) is to trigger an itti X2AP_SUBFRAME_PROCESS message (RRC->X2AP)  
This change avoids creating RRC_SUBFRAME_PROCESS message if x2ap task is not enabled
