Wanted to expand this to other functions like rte_eth_dev_configure()
but the structure rte_eth_conf has grown quite large
According to pahole
/* size: 2280, cachelines: 36, members: 8 */
/* sum members: 2268, holes: 2, sum holes: 8 */
/* padding: 4 */
/* member types with holes: 3, total: 4, bit holes: 1, total: 1, bit
paddings: 1, total: 29 bits */
The biggest offender
there is DCB and VMDQ both of which are features I doubt anyone ever uses,
but unlikely to get that fixed.
Because it is so large, it is impossible to pass rte_eth_conf over the mp
primary/secondary API.
