Br,shuva From: [email protected] [mailto:[email protected]] On Behalf Of Josh Hershberg Sent: Sunday, August 07, 2016 10:07 PM To: odl netvirt dev; [email protected]; Anil Vishnoi Subject: [openflowplugin-dev] openflow actions are out of order, break netvirt pipeline All, it seems that for at least some flows the actions are being written out of order. Here is one flow from the netvirt pipeline [1], printed to the logs one line before it is written to the md-sal. You can clearly see how the load to reg6 comes before the resubmit action. However, dump-flows gives the opposite order [2]. Something down the stack from netvirt is flipping the order. This is further confirmed from a tcpdump capture where you can see that in the OFPT_FLOW_MOD the resubmit is sent before the reg load ([3] if anyone really wants to break their head).
