[pox-dev] send packet from controller

[Silvia Fichera]

Hello,
I am having trouble sending packets from l3_learning controller to host.
I would like to send UDP packets but if I try to use normal socket from
controller I see no traffic (I minotired it with wireshark on all switches)
unless I send to itself (127.0.0.1).  I was also trying to make a switch
sending the controller generated packet in this way:

Although I have no traffic too.
I guess the problem is that I am missing something like

 self.connection.send(msg)

but I don't have any datapath connection with any switch since I want to
start the communication from the controller.
Is there an easier way to send these udp packets?

thanks
