Is there a known bug, either in Devstack or Horizon, that prevents Neutron
port binding details from being displayed? My googling did not find
anything.

As admin, I open a port's details, and in the Binding section at the end of
the page, all I get is a bold text "VNIC Type". The CLI command "openstack
port show" does provide the details. Also on a Xena Devstack, Horizon
displays them[1]. Horizon's setup.py seems to be identical on both releases,
as far as Neutron configuration is concerned.

Thanks for any input.

Bernd.
