Few questions (in ovn setup):

1. After I do an add-port, who is supposed to add the attached-mac in
external_ids? The doc says
"The MAC address programmed into the ``virtual hardware'' for this
interface..."
meaning vif mac address? The reason is in neutron based ovn setup I see mac
address of netron port (hence lport) is say "fa:16:3e:da:eb:0a" then the
interface mac id (of vm) is set to "fe:16:3e:da:eb:0a" and the attached-mac
is set to "fa:16:3e:da:eb:0a". So in ovn setup, is it vif mac of the
attached to the VM or some lport mac?

2. iface-status in external_ids in Interface. Who sets it? After add-port
and "ip link set <iface> up" this is not getting set as "active". Even if I
set it active using ovs-vsctl the port is not forarding packets out. The
tcpdump shoes icmp traffic from vm at that port but it goes nowhere.

3. Any consequence if "vm-id" in external_ids not set? Is that used by
openstack?

Thanks
