Hi Tim,
Just about the second part of your email:
> how are IETF SFC/NSH related API/plugin changes going?
I'm essentially finished with NSH encap support [1], just have to fix a few
bugs and write the tests. Then I will work on connecting port-chains together
so we can have SFC graphs, kind of like IETF's branching/reclassification "SFC
Encapsulation" chains (described with higher detail in the NSH draft).
> Can we expect to have attributes like path-id, encap type soon?
The NSH patch I mentioned above will allow NSH encap to be specified for both
port-chains and port-pairs and, if port-pairs do not support the port-chain's
encapsulation, it's up to the driver to SFC-Proxy the traffic accordingly (OVS
will install SFC-proxy flows, just like it does today by default, for MPLS).
Regarding the path-id, I was working on a patch to facilitate that [2], but we
ended up merging one focused only on enabling the path-id ("chain_id") [3]. So
we have both attributes now.

Subject: [openstack-dev] [tacker] [networking-sfc] Removing required port-id
from classifier
Hi Cathy,
I recall a while back discussing removing the required neutron port-id from the
classifier. We just finished up implementing VNFFG in Tacker and are hitting
this while testing. What is the plan to remove this requirement? Also, how
are IETF SFC/NSH related API/plugin changes going? Can we expect to have
attributes like path-id, encap type soon?
Thanks,
Tim Rozet
