  87 The USRP2 sink inputs 100 Megasamples per second / interpolation.
  88
  89 Input amplitude should be between 0.0 and 1.0.
  90
  91 To use the default ethernet device, leave interface blank. \
  92 For systems with only 1 USRP2, you may leave the mac address blank. \
  93 For multi-USRP2 systems, specify the mac address in the form 00:50:C2:85:3x:xx.
