Hi Tomas,
I’m not expert in Open Flow(I’m learning as I go) but I have asked our
expert guy and it did not know the concept of extension of match field. What is
the difference between an extension and an experimenter? I’m pretty sure what
I’m doing is an experimenter (it is what I did in ONOS for my match) anyway (I
have based my code on the Nicira one and I think they did extension. It is
where I mixed both, I think, in my understanding). I’ll extend the
MatchEntryDeserializerKey class and set the ExperimenterID to see if it works.
I’ll not be able to test it before 1-2 weeks. I have an emergency to
take care at the office since today.
I really appreciate your help.
Thanks,
Yann
