Comment 2 for bug 1838760

Security groups for trunk ports are not supported with iptables_hybrid driver and that is documented limitation.
According to our discussion on neutron meeting here is the plan for that:

1. update docs to write this info in more visible place(s) also, 2. fix tempest test to not run this part (or this test) on unsupported configuration, 3. Try to do some more "in Your face" change as tidwellr proposed
