	select NETFILTER_XTABLES
	help
	  ebtables is a general, extensible frame/packet identification
	  framework. Say 'Y' or 'M' here if you want to do Ethernet
	  filtering/NAT/brouting on the Ethernet bridge.

config BRIDGE_EBT_BROUTE
	tristate "ebt: broute table support"
	help
	  The ebtables broute table is used to define rules that decide between
	  bridging and routing frames, giving Linux the functionality of a
	  brouter. See the man page for ebtables(8) and examples on the ebtables
	  website.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_T_FILTER
	tristate "ebt: filter table support"
	help
	  The ebtables filter table is used to define frame filtering rules at
	  local input, forwarding and local output. See the man page for
	  ebtables(8).

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_T_NAT
	tristate "ebt: nat table support"
	help
	  The ebtables nat table is used to define rules that alter the MAC
	  source address (MAC SNAT) or the MAC destination address (MAC DNAT).
	  See the man page for ebtables(8).

	  To compile it as a module, choose M here.  If unsure, say N.

	  This option adds the among match, which allows matching the MAC source
	  and/or destination address on a list of addresses. Optionally,
	  MAC/IP address pairs can be matched, f.e. for anti-spoofing rules.

config BRIDGE_EBT_IP
	tristate "ebt: IP filter support"
	help
	  This option adds the IP match, which allows basic IP header field
	  filtering.

config BRIDGE_EBT_IP6
	tristate "ebt: IP6 filter support"
	depends on BRIDGE_NF_EBTABLES && IPV6
	help
	  This option adds the IP6 match, which allows basic IPV6 header field
	  filtering.

config BRIDGE_EBT_LIMIT
	tristate "ebt: limit match support"
	help
	  This option adds the limit match, which allows you to control
	  the rate at which a rule can be matched. This match is the
	  equivalent of the iptables limit match.

	  If you want to compile it as a module, say M here and read
	  <file:Documentation/kbuild/modules.txt>.  If unsure, say `N'.

config BRIDGE_EBT_MARK
	tristate "ebt: mark filter support"
	help
	  This option adds the mark match, which allows matching frames based on
	  the 'nfmark' value in the frame. This can be set by the mark target.
	  This value is the same as the one used in the iptables mark match and
	  target.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_PKTTYPE
	tristate "ebt: packet type filter support"
	help
	  This option adds the packet type match, which allows matching on the
	  type of packet based on its Ethernet "class" (as determined by
	  the generic networking code): broadcast, multicast,
	  for this host alone or for another host.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_STP
	tristate "ebt: STP filter support"
	help
	  This option adds the Spanning Tree Protocol match, which
	  allows STP header field filtering.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_VLAN
	tristate "ebt: 802.1Q VLAN filter support"
	help
	  This option adds the 802.1Q vlan match, which allows the filtering of
	  802.1Q vlan fields.

	  To compile it as a module, choose M here.  If unsure, say N.
#
# targets
#
config BRIDGE_EBT_ARPREPLY
	tristate "ebt: arp reply target support"
	depends on BRIDGE_NF_EBTABLES && INET
	help
	  This option adds the arp reply target, which allows
	  automatically sending arp replies to arp requests.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_DNAT
	tristate "ebt: dnat target support"
	help
	  This option adds the MAC DNAT target, which allows altering the MAC
	  destination address of frames.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_MARK_T
	tristate "ebt: mark target support"
	help
	  This option adds the mark target, which allows marking frames by
	  setting the 'nfmark' value in the frame.
	  This value is the same as the one used in the iptables mark match and
	  target.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_REDIRECT
	tristate "ebt: redirect target support"
	help
	  This option adds the MAC redirect target, which allows altering the MAC
	  destination address of a frame to that of the device it arrived on.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_SNAT
	tristate "ebt: snat target support"
	help
	  This option adds the MAC SNAT target, which allows altering the MAC
	  source address of frames.

#
# watchers
#
config BRIDGE_EBT_LOG
	tristate "ebt: log support"
	help
	  This option adds the log watcher, that you can use in any rule
	  in any ebtables table. It records info about the frame header
	  to the syslog.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_ULOG
	tristate "ebt: ulog support (OBSOLETE)"
	help
	  This option enables the old bridge-specific "ebt_ulog" implementation
	  which has been obsoleted by the new "nfnetlink_log" code (see
	  CONFIG_NETFILTER_NETLINK_LOG).

	  This option adds the ulog watcher, that you can use in any rule
	  in any ebtables table. The packet is passed to a userspace
	  logging daemon using netlink multicast sockets. This differs
	  from the log watcher in the sense that the complete packet is
	  sent to userspace instead of a descriptive text and that
	  netlink multicast sockets are used instead of the syslog.

	  To compile it as a module, choose M here.  If unsure, say N.

config BRIDGE_EBT_NFLOG
	tristate "ebt: nflog support"
	help
	  This option enables the nflog watcher, which allows to LOG
	  messages through the netfilter logging API, which can use
	  either the old LOG target, the old ULOG target or nfnetlink_log
	  as backend.

	  This option adds the nflog watcher, that you can use in any rule
	  in any ebtables table.

	  To compile it as a module, choose M here.  If unsure, say N.
