The "brctl show" command will also provide some very useful info such as
which interfaces are bridged and what the state of Spanning Tree is on
those interfaces.

# brctl show
bridge name     bridge id               STP enabled     interfaces
dev             8000.0050568954bc       no              eth0
                                                        eth1

prod 8000.000000000000 no

I think what needs to happen here to successfully recreate a layer 2 LAN
loop is to directly connect 2 ports that are in the same bridge.
