## Bridge module
## =============
##
##  Allows creation of Layer 2 software "bridge" network devices.  A
##  common use case is to merge together a hardware Ethernet device
##  with one or more WLANs so that several local devices appear to be
##  on the same network. Create a ``primary`` service to specify the
##  new device, and a ``members`` service to add constituent devices
##  to it.
