      MR1029 : Benetel driver update  
      This MR fixes an issue with the driver for the 4G Benetel RRUs.
      Power levels on the 5G side were adapted to avoid saturation of the signals. 
      5G performance is now the same as with USRP. 
      Support for 2 antennas for both 4G and 5G was added

      MR1046 : Add support for NR UL SC-FDMA up to 100 MHz
      
      MR1053Nr : pdcp nea2 security
      
      MR1049 : improve rfsim
      -Fix a regression 
      Earlier parameter reading was moved to an external thread,  
      Eventually the check at the end of the main was too early, 
      Declaration of  some extra parameters are now on command line
      -Enhancement: 
      use the rfsim as a server on UE side, so we can connect two xNB to one UE
      -Simplification: 
      remove rfsim flags that have been made for convergence with replay function in usrp driver, but this is useless as they changed their code
      -Fix a bug in ubuntu 20.04 (now the code is ready in whole OAI)
      
      
      MR1056 : Bugfix: NR BSR calculation
      Fixes a bug in the scheduler for BSR calculation. 
      Before, we might wrongly track the BSR of a UE and not schedule it anymore although it has data. 
      Should be fixed now and improve UL throughput.

      Fixup sched_ul_bytes logic · a3b1216b
      Robert Schmidt authored
      1) Only count new transmission as scheduled bytes (which is then
      compared against the BSR)
      
      2) When subtracting scheduled bytes after successful reception, subtract
      TBsize from correct HARQ process

      NSA: finalize nea2 security for gNB · 73f3a458
      Cedric Roux authored
      - a new section in the configuration file to select security algorithms,
        with new code to deal with it
      - cleanup CG-ConfigInfo: specs seem to indicate that we must not
        add mcg_RB_Config; the gNB has to deal with that
      - as a consequence, modify fill_default_rbconfig() that is called in
        every cases and needs security and bearer parameters
      
      The new section in the configuration file looks like:
      
          security = {
            # preferred ciphering algorithms
            # the first one of the list that an UE supports in chosen
            # valid values: nea0, nea1, nea2, nea3
            ciphering_algorithms = ( "nea0", "nea2" );
      
            # preferred integrity algorithms
            # the first one of the list that an UE supports in chosen
            # valid values: nia0, nia1, nia2, nia3
            integrity_algorithms = ( "nia0" );
          };

      NSA: first draft of nea2 security for gNB · 10e021e9
      Cedric Roux authored
      The code is forced to use nea2, no matter what the UE supports.
      
      After 2^18 PDCP packets, it will fail to work (we don't use HFN yet).
      
      These limitations will be fixed in later commits.
      
      The existing security function was not reused, because it does too
      much memory allocation and initializes the security context at each
      ciphering. So here comes nr_pdcp_security_nea2_cipher(). And also
      the ciphering is done inplace. To be changed if necessary.
