Hi Minoru, I implemented the "stats_reply_handler" as you said, but I cant
pass of this section in line 186 of
https://github.com/osrg/ryu/blob/master/ryu/app/ofctl_rest.py#L689-L725
(ofctl_rest.py
<https://github.com/osrg/ryu/blob/master/ryu/app/ofctl_rest.py#L689-L725%28ofctl_rest.py>
:
if msg.xid not in self.waiters[dp.id]:
print "msg.xid no inside self.waiters[dp.id]"
print ""
return
I get a message in return of a request, but the msg.xid is not in
self.waiters, but I supposed that it would be there because
"send_stats_request" of ryu/lib/ofctl_V1_0.py
do it, so please help me to understand how can I put the msg.xid inside my
waiters?
Im doing my best effort, please help me.
Regards,
Marlon Olaya
