 * to a variety of groups in a group chain, depending on the whether
 * MPLS labels are being pushed or not.
 * <p>
 * NOTE: We do not create MPLS ECMP groups as they are unimplemented in
 *       OF-DPA 2.0 (even though it is in the spec). Therefore we do not
 *       check the nextObjective meta to see what is matching before being
 *       sent to this nextObjective.
