Re: [openflowplugin-dev] openflowjava IOB Exception in netvirt csit

I spent some time trying to figure this out (too much probably...) :) and correct me if
I'm wrong but this IOBE is coming from a flow that already exists on the switch and not
one we are trying to program. I do notice in a test I did that the IOBE comes every
~3s which I think is our default polling of operational.
anyway, I *think* narrowed down the exact test case that introduces this, and then compared
the flow table before and after that test case. The only difference are these two flows:
cookie=0x8000006, duration=0.810s, table=21, n_packets=0, n_bytes=0, priority=10,ip,metadata=0x30d52/0xfffffe
cookie=0x8000006, duration=0.810s, table=26, n_packets=0, n_bytes=0, priority=5,ip,metadata=0x30d52/0xfffffe
full flow table here 
I am only able to check these things with our CSIT stuff. I tried to manually create a flow that
looks like the table=26 flow above (via NB rest) but couldn't figure it out. I think my trouble
was trying to give a mask to the metadata.
I didn't try with serialization disabled yet, as that is gonna take some time to figure out
how to toggle it with our CSIT.
