      hotfix: fix bad RLC UM packet creation · 26d68e9c
      Cedric Roux authored
      Running TCP DL traffic with one connected UE showed a lot of
      fluctuations in throughput. After analysis it was found that
      sometimes the RLC UM PDU was not correct. It contained one byte
      more than it should. On the receiver side, the TCP packet
      contained in the RLC packet seems to be rejected by the TCP
      stack of the UE (it has one byte more than it should),
      leading to a brutal reduction of the throughput, probably due
      to some congestion detection in the TCP implementation.
      Or something.
      This hotfix seems to solve the problem. Using iperf in downlink
      with a 5MHz eNB, we see no more fluctuations, the traffic is
      very steady at 16.8Mb/s, as reported by the iperf server running
      on the phone. (17.5 in the PHY plot of the T tracer.)
      A rewrite of both the MAC and RLC UM packet generation is needed.
      The code is way too complex for what it does and may contain
      several similar problems that only trigger in specific rare
