## Kernel Configuration

Enable the following options in the kernel configuration and recompile the kernel if necessary:

    [*] Networking support --->            [CONFIG_NET]
          Networking options --->
            <*/M> 802.1d Ethernet Bridging [CONFIG_BRIDGE]

## Installation of bridge-utils

Install bridge-utils by running the following commands:

    autoconf                  &&
    ./configure --prefix=/usr &&
    make

Testing the results requires running the six shell scripts in the `tools/` directory. Two of the tests require two ethernet ports. Some tests will not preserve the current network configuration. See `tests/README` for details.

Now, as the `root` user:

    make install
