Fixes bug 1227964
This fix ports the Cisco Nexus database and network database
unit tests to the Cisco ML2 mechanism driver UT.
The existing test scripts which are ported:
neutron/tests/unit/cisco/test_nexus_db.py
neutron/tests/unit/cisco/test_network_db.py
The new test scripts are:
neutron/tests/unit/ml2/drivers/test_cisco_nexus_db.py
neutron/tests/unit/ml2/drivers/test_cisco_network_db.py
Note that the QoS database related tests in
test_network_db.py are not ported because QoS is
not currently supported in the Cisco ML2
mechanism driver.
