Don't have test it,
but according to this post

Quote:If you include
smsc95xx.macaddr=B8:27:EB:59:EB:25
in your own cmdline.txt then start.elf won't set the default one.

ssh to the pi,

Terminal

sudo nano /boot/cmdline.txt
append this at the end of the line
smsc95xx.macaddr=B8:27:EB:59:EB:25 (with your desired Mac)
ctrl + x to save

reboot
