From: Huisong Li <lihuisong@huawei.com>

Use the testpmd to perform the following operations:
1) mac_addr add 0 00:18:2D:00:00:90
2) mac_addr add 0 00:18:2D:00:00:91
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:00:00:91
  00:18:2D:00:00:90
  00:18:2D:00:00:91
  00:18:2D:00:00:92

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.
