%description
A firewalling tool to transparently filter network traffic passing a
bridge. The filtering possibilities are limited to link layer filtering
and some basic filtering on higher network layers. The ebtables tool
can be used together with the other Linux filtering tools, like
iptables. There are no incompatibility issues.

%description -n libebtc0
libebtc ("ebtables cache") is used to retrieve from the kernel, parse,
construct, and load rulesets into the kernel.
