<div dir="ltr">How are you implementing the change? It would be good to get to see some code in a review to get an idea of what needs to be updated.
<div><br>
</div>
<div>If it's just a change in the DB base plugin, just let those changes propagate to the plugins that haven't overridden the inherited behavior.</div>

<div style="word-wrap:break-word">Hi all,
<div><br>
</div>
<div>I need some help regarding a bug [1] I'm working on.</div>
<div><br>
</div>
<div>The bug is basically a request to make the mac address of a port updatable. The use case is a baremetal (Ironic) node that has a bad NIC which must be replaced, resulting in a new mac address. The bad NIC has an associated neutron port which of course
holds the NIC's IP address. The reason to make mac_address updatable (as opposed to having the user create a new port and delete the old one) is that during the recovery process the IP address must be retained and assigned to the new NIC/port, which is not
guaranteed in the above work-around.</div>
<div><br>
</div>
<div>I'm coding the changes to do this in the ml2, openvswitch, and linuxbridge plugins but I'm not sure how to handle the the other plugins since I don't know if the associated backends are prepared to handle such updates. My first thought is to disallow
the update in the other plugins, but I would really appreciate your advice.</div>
<div><br>
</div>
<div>Kind regards,</div>
