Hi Ryu team:
Thank you for your patch. Now the error of "unpack_from" is gone.
However, there is still something wrong there: the length of msg.data after
parsing is always 0.
Here is part of our code:
*@handler.set_ev_cls(ofp_event.EventOFPPacketIn, handler.MAIN_DISPATCHER)*
* def packet_in_handler(self, event):*
* msg = event.msg*
* datapath = msg.datapath*
* dpid = datapath.id*
* in_port = msg.in_port*
*
*
* whole_packet = packet.Packet(msg.data)*
* ethernet_header = whole_packet.get_protocol(ethernet.ethernet)*
* ethernet_src = ethernet_header.src*
The last statement (*ethernet_src = ethernet_header.src*) triggers an error:
*AttributeError: 'NoneType' object has no attribute 'src'*
*
*
I tried to debug the problem, and found out that the length of data is 0.
