Comment 7 for bug 1586056

From what I see in the drivers meeting log, and my conversation with Ihar on IRC http://eavesdrop.openstack.org/irclogs/%23openstack-neutron/%23openstack-neutron.2016-06-17.log.html#t2016-06-17T11:05:55

We seem have consensus on doing the validation part, while leaving the extra reporting ("$ neutron qos-rule-support-per-port-type") for a separate RFE if we still find it necessary and we find a reasonable way to do it (vnic type vs binding type vs tenant visibility of binding type)
