Comment 13 for bug 1602681

It is stated in http://paste.openstack.org/show/531701/ that we get the exception when system_test/tests/actions_base.py test is executed. The thing is that we do not use such kind of test in stable/6.1 and stable/7.0.

On the other hand we do not even use ironic_net.subnet in 6.1 and 7.0 fuel-qa. Closing as invalid for those branches.
