Random MAC addresses?

[pygr]

Hi,

I have a ClearFog Base, which has 3 ethernet interfaces. On every boot, ifconfig shows different (random?) MAC addresses for the 3. If I set a MAC address in u-boot with

setenv eth1addr 00:50:43:02:02:00

or in the device tree with Mac-address

mac-address = [00 50 43 02 02 00]

, it doesn't make any difference. The MAC address after booting into the OS still seems to be random.

What's up with that?

Hello,
There is an thread about this in the ARM mailing list about the reason why. But you can have a persistent MAC address by specify it in rc.conf. Eg.

ifconfig_xxx0="DHCP ether aa:bb:cc:dd:ee:ff"
