Yes, it's because of the order.
We should refactor this to use array designators.

+1 on using RSVD1 so it matches rte_vxlan_hdr definition.
In this patch, "vxlan_last_rsvd" is used in testpmd, so it matches existing
"last_rsvd" field in VXLAN item.
If we choose to use "rsvd1", we should probably rename all other instances of
"last_rsvd" to match.
