tool: D10: -d destination_addr establish a association with the specified address


tool: D148: -l length           number of bytes of the payload when generating traffic (default 512)


tool: D61: -m                  print number of received bytes and chunks per period (see -p)


tool: D167: -M                  print number of received bytes, chunks per period (see -p) and flow control info


tool: D99: -n number           number of packets initially send out (default 0)
