Hello,
Just to keep registry
I don't know why it did not worked as i configured. I think is something
related to how the cpdq SW verify the speed of pactes sent to the
controller.
Ether way i change flags=ofproto.OFPMF_KBPS to flags=ofproto.OFPMF_PKTPS
and i was able to see that i only received packeg in events in blocks of 10
pkts.
So it is working.
Before i came up with this change i evaluated the meter table and was able
to see that pkts were hitig it. So the send to controller flow (table miss)
was beeing "metering" but it wasing woking for some reason.. so i change to
OFPMF_PKTPS and worked!
Hope this will help someone else
Thabks
