[LEDE-DEV] ar71xx: Non-Unique MAC addresses for GL-iNet GL-AR750

[Sven Eckelmann]

Hi,

I've just noticed that the mac addresses for this device aren't unique (on the 
device itself). Neither in the original firmware or in the OpenWrt/LEDE 
support.

2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
    link/ether e4:95:6e:44:09:58 brd ff:ff:ff:ff:ff:ff
5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
    link/ether e4:95:6e:44:09:58 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel state DOWN qlen 1000
    link/ether e4:95:6e:44:09:59 brd ff:ff:ff:ff:ff:ff
4: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
    link/ether e4:95:6e:44:09:59 brd ff:ff:ff:ff:ff:ff

The address for eth0 is in the art partition (offset 0x0) and the rest are 
calculated manually based on that. Now it would be interesting to know how 
many addresses were actually allocated per device for the GL-AR750. The 
devices which I've received seem to suggest that at max 4 mac addresses are 
assigned per device (but maybe also only 2) and I can only hope that at least 
two were allocated.

Kind regards,
	Sven
