  	---help---
  	  If you say Y here, then your Linux box will be able to act as an
  	  Ethernet bridge, which means that the different Ethernet segments it
  	  is connected to will appear as one Ethernet to the participants.
  	  Several such bridges can work together to create even larger
  	  networks of Ethernets using the IEEE 802.1 spanning tree algorithm.
  	  As this is a standard, Linux bridges will cooperate properly with
  	  other third party bridge products.
  
  	  In order to use the Ethernet bridge, you'll need the bridge
  	  configuration tools; see <file:Documentation/networking/bridge.txt>
  	  for location. Please read the Bridge mini-HOWTO for more
  	  information.
  
  	  If you enable iptables support along with the bridge support then you
  	  turn your bridge into a bridging IP firewall.
  	  iptables will then see the IP packets being bridged, so you need to
  	  take this into account when setting up your firewall rules.
  	  Enabling arptables support when bridging will let arptables see
  	  bridged ARP traffic in the arptables FORWARD chain.
  
  	  To compile this code as a module, choose M here: the module
  	  will be called bridge.
  
  	  If unsure, say N.

  	---help---
  	  If you say Y here, then the Ethernet bridge will be able selectively

  	  forward multicast traffic based on IGMP/MLD traffic received from
  	  each port.

  
  	  Say N to exclude this support and reduce the binary size.
  
  	  If unsure, say Y.
