mobipass standalone driver

Browse Source 
How to use:

1 - compilation of softmodem:
  ./build_oai --eNB -t ETHERNET

2 - compilation of mobipass driver:
  cd cmake_targets/lte_build_oai/build
  make oai_mobipass
  ln -sf liboai_mobipass.so liboai_transpro.so

3 - configuration:
  edit the configuration file, set "node_timing" to
  "synch_to_mobipass_standalone"
  that is, have the line:
    node_timing               = "synch_to_mobipass_standalone";

4 - run:
  run as usual: sudo ./lte-softmodem -C <configuration file>
