I can remove this part (rte_eth_config), but the new API provides other link information which is not available from the existing API, like supported/advertising/partner_advertising link modes.

Additionally from what I see, rte_eth_confg is available from rte_eth_dev_conf_get API and it's copy of requested configuration:

`memcpy(dev_conf, &dev->data->dev_conf, sizeof(struct rte_eth_conf));`

DPDK already had this info under rte_eth_conf and it is supported
on all drivers. Why introduce yet another API and only for some drivers?
