add a flow entry together with table miss entry in every switch in the topology when starting the ryu controller.

[chitsukhin]

Hello! everyone advise me plz....
I wanna to add flow entry together with table miss entry in every switch in the topology when starting the ryu controller.
the flow entry that i want to added is

match = parser.OFPMatch(in_port=in_port, eth_dst=('33:33:00:00:00:fb'))
actions = drop

I edit the code to add a flow in simple-switch_13.py

_@set_ev_cls(ofp_event.EventOFPSwitchFeatures, CONFIG_DISPATCHER)
def switch_features_handler(self, ev):
datapath = ev.msg.datapath
ofproto = datapath.ofproto
parser = datapath.ofproto_parser

# install the table-miss flow entry.
match = parser.OFPMatch()
matchmulti = parser.OFPMatch(in_port=in_port, eth_dst=('33:33:00:00:00:fb'))
actions = [parser.OFPActionOutput(ofproto.OFPP_CONTROLLER,
                                  ofproto.OFPCML_NO_BUFFER)]
actionsmulti = [parser.OFPActionOutput(ofproto.OFPP_FLOOD)]        
self.add_flow(datapath, 0, match, actions)
self.add_flow(datapath, 0, matchmulti, actionsmulti)_
