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
