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

  20         help
  21           The ebtables broute table is used to define rules that decide between
  22           bridging and routing frames, giving Linux the functionality of a
  23           brouter. See the man page for ebtables(8) and examples on the ebtables
  24           website.

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

  90           This option adds the limit match, which allows you to control
  91           the rate at which a rule can be matched. This match is the
  92           equivalent of the iptables limit match.
  93

 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

 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.

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