I'm all for using rte_flow in any case. I've already documented an approach
to convert TUNNEL filter rules to rte_flow rules [1], although it may be
incomplete due to my limited experience with this filter type. We already
know several tunnel item types must be added (currently only VXLAN is

I understand ixgbe/i40e currently map rte_flow on top of the legacy
framework, therefore extending this structure might still be needed in the
meantime. Not sure we should prevent this change as long as such rules can
be configured through rte_flow as well.
