    sys/net              if_bridge.c if_bridgevar.h 
  Add a bridge interface flag called PRIVATE where any private port can not
  communicate with another private port.
  All unicast/broadcast/multicast layer2 traffic is blocked so it works much the
  same way as using firewall rules but scales better and is generally easier as
  firewall packages usually do not allow ARP blocking.
  An example usage would be having a number of customers on separate vlans
  bridged with a server network. All the vlans are marked private, they can all
  communicate with the server network unhindered, but can not exchange any
  traffic whatsoever with each other.
