As I can see mac_addr_set() is implemented now only for virtio.
Which means that for all Intel HW your new rte_eth_dev_default_mac_addr_set()
would not work right now?
Probably rte_eth_dev_default_mac_addr_set() should combine both approaches:
If mac_addr_set() is implemented by dev, then use it, otherwise try to use addr_remove()/addr_add()
(as your first version did)?
