Firstly no struct element has been removed from struct rte_eth_dev {} in the
eth_dev patch.
A dev_flags element has been added to struct rte_eth_dev{}
A numa_node element has been added to struct rte_eth_dev_data{}.
Unmodified VDEV's and PDEV's will not be aware of these new elements and will
be unaffected by the eth_dev changes.
Regards,
Bernard.
