Yi,
I installed your OVS NSH patch, and also built ODL with your
OpenFlowPlugin and SFC patches and am able to get the below NSH flows
that look good to me.
Once we get the patches merged in ODL, we can start working on using
this in the OPNFV SFC Colorado release.
Nice work :)
Regards,
Brady

*Subject:* Re: [opnfv-tech-discuss] [sfc-dev] ovs nsh patches are
available for public use
- what minimum linux kernel is required? OVS version?
This depends on ovs itself, current ovs git master
- I thought there were changes needed to the kernel, but these look to
be all ovs patches
ovs includes kernel modules, but to upstream them, kernel modules must
be accepted by Linux firstly, our team is working on this, but
progress is very slow.
- do we need the related kernel gpe patch?
Jiri has pushed gpe patch, but that only support L3 mode, but current
ovs requires it in L2 mode, they didn’t make an agreement on this
work, progress will be slow.
- what versions of linux distributions have been used?
It is distribution agnostic, just build it as before.
- eth_nsh is not in the odl ovsdb - is a patch needed there also?
- does openflowplugin require support?
Yes, https://git.opendaylight.org/gerrit/30481 is for your reference,
will update it to adapt to these patches.

Yang,
Thanks for this!
We'll start looking into using this now.
Do you know what's the latest status of getting NSH into OVS
officially? What's the difference between this patch in your
github and what will be available officially?
What are the system requirements for using your patch, like Linux
kernel, OVS, etc. It doesnt look like it, but is DPDK needed with
this patch?
Thanks,
Brady
