[ovs-discuss] [ovn] API related questions

[Murali R]

Please clarify on the following:

- There are external_ids associated with lport in ovn-nbctl. Is there any
requirement that this must be NULL right now? Does it matter if there is a
name (for instance port name in neutron).

- Is there any relationship between external_ids defined in lport in nb-db
and the Interface based external_ids such as iface_id ? Meaning can I have
a name defined in nb-db for neutron port-name that may not be in any way
related to iface_id or any name parameter in ovsdb port / Interface?

- Is there any requirement for mac_id to be same between iface in ovsdb and
lport? I see just second nibble differs fa vs fe in openstack based
deployment, not sure if that is a neutron/nova quirk or an ovn requirement.

- I don't see dedicated api for modifying logical flows? Do we need to use
ovn-sbctl set Pipeline <field>=<value>.... ?


Thanks
Murali
