It seems you misunderstood the cover letter. The HW will still
identify MPLS (IPv4/IPv6) packets using a new bit we specify in the HW
steering rules rather than adding new specific rules with {MPLS
ethertype} X {IPv4,IPv6} to classify MPLS IPv{4,6} traffic, Same
functionality a better and general way to approach it.
Bottom line the hardware is capable of processing MPLS headers and
perform RSS on the inner packet (IPv4/6) without the need of the
driver to provide precise steering MPLS rules.
