> The rte_flow_item_eth and rte_flow_item_vlan items are refined.
> The structs do not exactly represent the packet bits captured on the
> wire anymore.
> Should use real header instead of the whole struct.
>
> Replace the rte_flow_item_* with the existing corresponding rte_*_hdr.

> Fixes: 09315fc83861 ("ethdev: add VLAN attributes to ethernet and VLAN items")

This constant should be used above in hairpin functions.
Will change while merging.
