  11           If you say Y here, then your Linux box will be able to act as an
  12           Ethernet bridge, which means that the different Ethernet segments it
  13           is connected to will appear as one Ethernet to the participants.
  14           Several such bridges can work together to create even larger
  15           networks of Ethernets using the IEEE 802.1 spanning tree algorithm.
  16           As this is a standard, Linux bridges will cooperate properly with
  17           other third party bridge products.
  18
  19           In order to use the Ethernet bridge, you'll need the bridge
  20           configuration tools; see <file:Documentation/networking/bridge.txt>
  21           for location. Please read the Bridge mini-HOWTO for more
  22           information.
  23
  24           If you enable iptables support along with the bridge support then you
  25           turn your bridge into a bridging IP firewall.
  26           iptables will then see the IP packets being bridged, so you need to
  27           take this into account when setting up your firewall rules.
  28           Enabling arptables support when bridging will let arptables see
  29           bridged ARP traffic in the arptables FORWARD chain.

  31           To compile this code as a module, choose M here: the module
  32           will be called bridge.

  34           If unsure, say N.

  42           If you say Y here, then the Ethernet bridge will be able selectively
  43           forward multicast traffic based on IGMP/MLD traffic received from
  44           each port.
  45
  46           Say N to exclude this support and reduce the binary size.

  48           If unsure, say Y.

  55         ---help---
  56           If you say Y here, then the Ethernet bridge will be able selectively
  57           receive and forward traffic based on VLAN information in the packet
  58           any VLAN information configured on the bridge port or bridge device.
  59
  60           Say N to exclude this support and reduce the binary size.

  62           If unsure, say Y.
