This topic is a little bit old, but it is difficult to find answer to this question. Changing /etc/network/interfaces don't work on Angstrom Linux (provided by Terasic).
To permanently set MAC address, you need to abort booting procedure by pressing any key (which will give you access to U-Boot) and then type:
setenv ethaddr 00:11:22:33:44:55
saveenv
I hope this will help people looking for answer.

I am also seeing the problem where my MAC address is randomized on reboot. I have tried setting the ethaddr in the uboot environment, but it appears this variable is not being passed to the llinux kernel. The ethaddr variable in the uboot environment remains the same after each reboot, but the MAC address assigned to this interface by linux is random. We are running Angstrom v2014.12 on the Arria 10 SoC. We are using the reference design from rocketboards. Do you have any idea why this is happening?
