Description Sridhar Gaddam 2017-02-23 08:40:33 UTC 
Description of problem:

The following patch in Neutron[1] modifies the Network delete sequence.
Prior to a network delete event, we now see an update event that removes
the networkType. So, in delete event, when we try to check for the
networkType, it would be empty and there is an exception. Because of this,
elanInstances are not getting deleted. In this patch, we avoid the check
for networkType since the network itself would not be created in the first
place if its not a supported networkType.

Version-Release number of selected component (if applicable):


How reproducible:
always.

Steps to Reproduce:
1. In a fresh installation create a tenant neutron network, subnet and router.
2. Associate the subnet to the neutron router.
3. In karaf cli, check the ELAN instances.
   opendaylight-user@root>elan:show 
4. You would see an ELAN instance created for the resources.
5. Now dissociate the tenant subnet from neutron router, delete the router, network and subnet.

Actual results:
Check elan instances. You will see the same output as in Step 3 above.

Expected results:
The ELAN instances should have been deleted.
