<p class="MsoNormal" style="text-indent:-5.25pt"><span style="font-size:10.0pt;font-family:Consolas;color:black">Both proposals sound similar, so it's great that we are converging. I think that it's important that we put more details in each BP on what's exactly
covered by it. One question I have is about where binding:profile will be implemented. I see that portbinding is defined/implemented under its extension and neutron.db. So when both of you guys are saying that implementing binding:profile in
<b><i>ML2</i></b>, I'm kind of confused. Please let me know what I'm missing here. My understanding is that non-ML2 plugin can use it as well.<o:p></o:p></span></p>
<p class="MsoNormal"><b><i><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">[IrenaB] Basically you are right. Currently ML2 does not inherit the DB Mixin for port binding. So it supports the port binding extension, but uses its
own DB table to store relevant attributes. Making it work for ML2 means not adding this support to PortBindingMixin.

<div>
<p class="MsoNormal" style="text-indent:-5.25pt"><span style="font-size:10.0pt;font-family:Consolas;color:black">Another issue that came up during the meeting is about whether or not vnic-type should be part of the top level binding or part of binding:profile.
In other words, should it be defined as binding:vnic-type or binding:profile:vnic-type. <o:p></o:p></span></p>

</span></i></b><span style="font-size:10.0pt;font-family:Consolas;color:#1F497D">As long as existing binding capable Mech Drivers will take vnic_type into its consideration, I guess doing it via binding:profile will introduce less changes all over (CLI, API).
But I am not sure this reason is strong enough to choose this direction<o:p></o:p></span></p>

<p class="MsoNormal" style="text-indent:-5.25pt"><span style="font-size:10.0pt;font-family:Consolas;color:black">We also need one or two BPs to cover the change in the neutron port-create/port-show CLI/API.<o:p></o:p></span></p>
