SFC classifying traffic into non symmetric paths

SFC classifier might classify uplink and downlink traffic into paths that are not symmetric to each other. This happens due to the combined facts:

• From Oxygen, SFC translator uses the SFP redirect action instead of the RSP redirect action, to support symmetric path classification.
• From Oxygen, SFC automatically creates appropriate RSPs for any configured SFP.
• SFC transaltor also explicitly creates the required RSPs from any translated port chain -> SFP. For symmetric paths, this results in multiple RSPs symmetric to each other in pairs associated to the SFP.
• The Classifier picks two RSPs associated to the SFP in the ACL SFP redirect action for symmetric traffic, but does not check that those two are indeed a pair of symmetric paths. Thus a SF might be in one path but not the other and will not see all the traffic.
