26 The ebtables broute table is used to define rules that decide between
27 bridging and routing frames, giving Linux the functionality of a
28 brouter. See the man page for ebtables(8) and examples on the ebtables
29 website.

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

98 the rate at which a rule can be matched. This match is the
99 equivalent of the iptables limit match.

200 which has been obsoleted by the new "nfnetlink_log" code (see
201 CONFIG_NETFILTER_NETLINK_LOG).
202
203 This option adds the ulog watcher, that you can use in any rule
204 in any ebtables table. The packet is passed to a userspace
205 logging daemon using netlink multicast sockets. This differs
206 from the log watcher in the sense that the complete packet is
207 sent to userspace instead of a descriptive text and that
208 netlink multicast sockets are used instead of the syslog.
