The expansion function gets an item tree for the above adjustment from the caller which reflects the HW needs. The standard vxlan header next protocol is always ethernet while there are some Mellanox customers who use their own method to allow L3 headers after the vxlan tunnel header. The expansion tree of mlx5 PMD didn't expect to get L3 headers after the vxlan header what caused a failure in flow creation when inner RSS is requested on L3 after vxlan flow. Add IPV4 and IPV6 as optional headers after vxlan in the RSS expansion tree to allow L3 tunnel support for vxlan.
