      1 ## Bridge module
      2 ## =============
      3 ##
      4 ##  Allows creation of Layer 2 software "bridge" network devices.  A
      5 ##  common use case is to merge together a hardware Ethernet device
      6 ##  with one or more WLANs so that several local devices appear to be
      7 ##  on the same network.
