  - Support sfp redirect action on acl flow check

    Starting Oxygen, ODL networking-sfc translator supports symmetric
    paths and maps flow classifiers to ACLs with SFP redirect action
    instead of RSP redirect action. A SFP may have two RSPs associated
    if the path is symmetric, one otherwise. One of the two RSPs will
    be flagged as the reverse path and the other is the forward path.
    Traffic from the logical-source-port will be classified to the forward
    path, while traffic from the logical-destination-port will be
    classified to the reverse path.

    This patch updates the ACL flow check logic to account for the above.
