Badri,

all that is needed for OepnStack and ODL integration is the odl-ovsdb-openstack feature.

If the list from Helium here is why they are no longer needed:

odl-base-all odl-aaa-authn odl-restconf: there was a bug with authn and restconf where they had to be installed in a certain order.

odl-nsf-all odl-adsal-northbound: needed for the odl-ovsdb-northbound

odl-mdsal-apidocs odl-dlux-core: only if you wanted dlux. This is not needed for openstack integration, it was just something to use if you wanted to use dlux to view the topology

odl-ovsdb-northbound: this is deprecated for Li. It can still be used, but you would also need to load the odl-ovsdb-plugin and not load odl-ovsdb-openstack. In this case you would not have openstack integration, you would see ovsdb events, but nothing from the neutron or openstack integration.

Thanks, Sam
