In order to use the Ethernet bridging functionality, you'll need the userspace tools. Documentation for Linux bridging is on: http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge The bridge-utilities are maintained at: git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/bridge-utils.git Additionally, the iproute2 utilities can be used to configure bridge devices. If you still have questions, don't hesitate to post to the mailing list (more info https://lists.linux-foundation.org/mailman/listinfo/bridge).
