Previously, the only way to query the flow table was to run "ovs-ofctl dump-flows". This returned most flows, but not those marked hidden by secchan. Hidden flows are setup by mechanisms such as in-band control, since they must not be modified by users of the controller. However, when debugging problems on the switch, it is often useful to see what the flow table is actually doing. The new "bridge/dump-flows" command added to ovs-appctl shows all flows being used by the OpenFlow stack.
