+The ebtables program is a filtering tool for a Linux-based bridging firewall. It
+enables transparent filtering of network traffic passing through a Linux bridge.
+The filtering possibilities are limited to link layer filtering and some basic
+filtering on higher network layers. Advanced logging, MAC DNAT/SNAT and brouter
+facilities are also included.
+
+The ebtables tool can be combined with the other Linux filtering tools (iptables,
+ip6tables and arptables) to make a bridging firewall that is also capable of
+filtering these higher network layers. This is enabled through the
+bridge-netfilter architecture which is a part of the standard Linux kernel.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+ebtables:
+ebtables: The ebtables utility enables basic Ethernet frame filtering on a
+ebtables: Linux bridge, logging, MAC NAT and brouting. It only provides basic
+ebtables: IP filtering, the full-fledged IP filtering on a Linux bridge is
+ebtables: done with iptables.
