Tool 156: Network performance measurement : TCP client
  
  Description:
   
  This tool connects on tool 155. It permits to measure throughput and
  jitter for TCP. So, tool 155 is ran on one computer, and tool 156 on
  another.
  
  Parameter --chunksize changes the size of data used for each step.
  Parameter --duration defines the duration of test in milliseconds.
  Parameter --dst-ip is the address of remote host/server.
  Parameter --dst-port is the port number where to connect.
  Optional parameter --src-ip defines the local IP address to use.
  Optional parameter --src-port defines the local port number to use.
  Optional parameter --ip4opts permits to add IP4 options encoded as
  mixed.
  Optional parameter --ip6exts permits to add IP6 options encoded as
  mixed (first byte is the next header number).
  Optional parameters --device, --src-eth and --dst-eth permits to
  create a virtual client using fake addresses (in this case, tool have
  to be run with admin privilege in order to sniff and spoof at
  Ethernet level).
