We should match on the transport ports only if the tunnel has a UDP header. It doesn't make sense to match on transport port for GRE tunnels.
Also, to match on fragment bits we should use FLOW_NW_FRAG_MASK instead of 0xFF. FLOW_NW_FRAG_MASK is what we get if we convert to the ODP netlink format and back. Adding the correct masks in the tunnel router classifier helps in making sure that the translation generates a masks that respects prerequisites. If the mask has some fields that do not respect prerequisites, the flow will get deleted by revalidation, because translating to ODP format and back will generate a more generic mask, which will be perceived as too generic (compared with the one generated by the translation).
