This commit enables UL traffic in do-ra mode by doing two changes: - configure SDAP to send traffic to TUN interface instead of GTP by abusing enb_flag=0 (i.e., setting UE mode for gNB SDAP) - manually enable RLC LCID in UE MAC, since nr_DRB_preconfiguration() statically enables one DRB bearer, without notifying MAC
