I think we are supposed to behave like Nova, binding wise.

@Banix: Can you confirm that it is a bug and not a feature?

>From a quick grepping I see hat nova sets the name to be:

    nova/network/neutronv2/api.py:                devname = "tap" +
current_neutron_port['id']

Whereas in Kuryr we use the first 8 characters of the Docker endpoint id.
