From: Laurent Hardy <laurent.ha...@6wind.com>

When a new mac address is set, it is saved in dev->data->mac_addrs
before the ethdev handler is called.

First, it is inconsistent with the other ethdev functions
rte_eth_dev_mac_addr_remove() and rte_eth_dev_mac_addr_add().

Moreover, it prevents the drivers from wrongly comparing the old address
and the new one, like it's done in i40evf driver:

        if (is_same_ether_addr(mac_addr, dev->data->mac_addrs))
                return;

Fixes: 943c2d899a0c ("net/i40e: set VF MAC from VF")
Fixes: 854d8ad4ef68 ("ethdev: add default mac address modifier")
