Open Stack

Hi together, 
for a new ml2 plugin I would like to pass over some data from neutron to
nova on port creation and update (exploiting port binding extension
[1]). For my prototype I thought of using one of the following response
dictionaries to add my information:

- binding:vif_details
- binding:profile

The API ref describes these attributes (port create / port update - both
response) as dictionaries, but without restricting the key-value pairs
or naming a defined number [1]. 

I've also seen some other ml2 plugins enriching those fields with unique
data. So I assuming this is not considered as an API change, isn't it?

Important: It's only about the response. The input comes from a
configuration file.


Thanks
