I have a bearmetal setup which has 2 LAN ports using the same network chip.
I've set `netif_num=2 mac1=****** mac2=******`, but only mac1 is working. The second LAN port still stay the original MAC inside DSM.
But here is the interesting part: I created a bond using these two ports and deleted the bond. Then the mac1 and mac2 are both working.
But after reboot, mac2 returns to the original value.
