With that mac, mtu as optional input fields provide the necessary
flexibility

for different stacks to take appropriate shape as they desire.


Thanks for the clarification. I think we'd better document the above
in the patch that introduces the mac setting from management API.

Yes. Will do.
Thanks.

Adding Sean.

Regarding to mac address setting. Do we plan to allow to modify mac
address after the creation? It looks like Openstack wants this.

Mac address is exposed in the features so yes, it should be possible to modify it as part of features modify command. (in future).
User needs to make sure that device is not attached to vhost or higher layer stack when device configuration layout is modified.
 

Sean may share more information on this.

Thanks
