+config BRIDGE
+ tristate "802.1d Ethernet Bridging"
+ select LLC
+ select STP
+ depends on IPV6 || IPV6=n
+ 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.rst>
+ 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.
+
+config BRIDGE_IGMP_SNOOPING
+ bool "IGMP/MLD snooping"
+ depends on BRIDGE
+ depends on INET
+ default y
+ 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.
+
+config BRIDGE_VLAN_FILTERING
+ bool "VLAN filtering"
+ depends on BRIDGE
+ depends on VLAN_8021Q
+ default n
+ help
+ If you say Y here, then the Ethernet bridge will be able selectively
+ receive and forward traffic based on VLAN information in the packet
+ any VLAN information configured on the bridge port or bridge device.
+
+ Say N to exclude this support and reduce the binary size.
+
+ If unsure, say Y.
+
+config BRIDGE_MRP
+ bool "MRP protocol"
+ depends on BRIDGE
+ default n
+ help
+ If you say Y here, then the Ethernet bridge will be able to run MRP
+ protocol to detect loops
+
+ Say N to exclude this support and reduce the binary size.
+
+ If unsure, say N.
+
+config BRIDGE_CFM
+ bool "CFM protocol"
+ depends on BRIDGE
+ help
+ If you say Y here, then the Ethernet bridge will be able to run CFM
+ protocol according to 802.1Q section 12.14
+
+ Say N to exclude this support and reduce the binary size.
+
+ If unsure, say N.
