Public bug reported:

Instead of using neutron.tests.base.get_rand_device_name(), sanity check
tests have been generating their own prefix name and appending a random
string with utils.get_rand_name(). Many of the strings generated were
too long to be device names, so ovs-vswitchd would fail to create the
devices.

For example:

2016-03-18T05:40:41.950Z|07166|dpif|WARN|system@ovs-system: failed to query port patchtest-b76adc: Invalid argument
2016-03-18T05:40:41.950Z|07167|dpif|WARN|system@ovs-system: failed to add patchtest-b76adc as port: Invalid argument
