> 3) mac_addr add 0 00:18:2D:00:00:92
> 4) mac_addr set 0 00:18:2D:00:00:91
> 5) show port 0 macs
> Number of MAC address added: 4

>   00:18:2D:00:00:92

Please describe with words.
Reading similar MAC addresses is not a fun game.

> This is due to the reason that if the address has been added as a
> non-default MAC address by rte_eth_dev_mac_addr_add API, it doesn't remove
> from dev->data->mac_addrs[] when set default MAC address with the same
> address.
