At startup enumerate datapath and port types and add this information to the datapath_types and port_types columns in the ovsdb. This allows an ovsdb client to query the datapath in order to determine if certain datapath and port types exist. For example, by querying the port_types column, an ovsdb client will be able to determine if this instance of ovs-vswitchd was compiled with DPDK support. Signed-off-by: Mark D.
