95 <file:Documentation/kbuild/modules.txt>. If unsure, say `N'.
97 config BRIDGE_EBT_MARK
98 tristate "ebt: mark filter support"
99 depends on BRIDGE_NF_EBTABLES
101 This option adds the mark match, which allows matching frames based on
102 the 'nfmark' value in the frame. This can be set by the mark target.
103 This value is the same as the one used in the iptables mark match and
106 To compile it as a module, choose M here. If unsure, say N.
108 config BRIDGE_EBT_PKTTYPE
109 tristate "ebt: packet type filter support"
110 depends on BRIDGE_NF_EBTABLES
112 This option adds the packet type match, which allows matching on the
113 type of packet based on its Ethernet "class" (as determined by
114 the generic networking code): broadcast, multicast,
115 for this host alone or for another host.
117 To compile it as a module, choose M here. If unsure, say N.
119 config BRIDGE_EBT_STP
120 tristate "ebt: STP filter support"
121 depends on BRIDGE_NF_EBTABLES
123 This option adds the Spanning Tree Protocol match, which
124 allows STP header field filtering.

128 config BRIDGE_EBT_VLAN
129 tristate "ebt: 802.1Q VLAN filter support"

139 config BRIDGE_EBT_ARPREPLY
140 tristate "ebt: arp reply target support"
141 depends on BRIDGE_NF_EBTABLES && INET
143 This option adds the arp reply target, which allows
144 automatically sending arp replies to arp requests.
146 To compile it as a module, choose M here. If unsure, say N.
148 config BRIDGE_EBT_DNAT
149 tristate "ebt: dnat target support"
150 depends on BRIDGE_NF_EBTABLES
152 This option adds the MAC DNAT target, which allows altering the MAC
153 destination address of frames.
155 To compile it as a module, choose M here. If unsure, say N.
157 config BRIDGE_EBT_MARK_T
158 tristate "ebt: mark target support"
159 depends on BRIDGE_NF_EBTABLES
161 This option adds the mark target, which allows marking frames by
162 setting the 'nfmark' value in the frame.
163 This value is the same as the one used in the iptables mark match and
166 To compile it as a module, choose M here. If unsure, say N.
168 config BRIDGE_EBT_REDIRECT
169 tristate "ebt: redirect target support"
170 depends on BRIDGE_NF_EBTABLES
172 This option adds the MAC redirect target, which allows altering the MAC
173 destination address of a frame to that of the device it arrived on.
175 To compile it as a module, choose M here. If unsure, say N.
177 config BRIDGE_EBT_SNAT
178 tristate "ebt: snat target support"

188 config BRIDGE_EBT_LOG
189 tristate "ebt: log support"
190 depends on BRIDGE_NF_EBTABLES
192 This option adds the log watcher, that you can use in any rule
193 in any ebtables table. It records info about the frame header
196 To compile it as a module, choose M here. If unsure, say N.
198 config BRIDGE_EBT_ULOG
199 tristate "ebt: ulog support (OBSOLETE)"
200 depends on BRIDGE_NF_EBTABLES
202 This option enables the old bridge-specific "ebt_ulog" implementation
203 which has been obsoleted by the new "nfnetlink_log" code (see
204 CONFIG_NETFILTER_NETLINK_LOG).
206 This option adds the ulog watcher, that you can use in any rule
207 in any ebtables table. The packet is passed to a userspace
208 logging daemon using netlink multicast sockets. This differs
209 from the log watcher in the sense that the complete packet is
210 sent to userspace instead of a descriptive text and that
211 netlink multicast sockets are used instead of the syslog.
213 To compile it as a module, choose M here. If unsure, say N.
