NoviFlow pipeline recirculation port issue resulting in lower network throughput

[viniarck]

If you create an EVC that has vlan translation, uni_a vlan 100 and uni_z vlan 200 for instance, uni_a will have a set_field vlan 200, push vlan, set field vlan xx (service vlan), in this case recirculation on the NoviFlow pipeline which can lead to lower network throughput since it'll internally consume more bandwidth chipset capacity.

If the same vlan is used, it won't happend, as it has been optimized on this prior PR #390

The solution for this still needs to be researched
