velo,
The MAC address printed on the sticker is the right one, always. You'll need to set it in your network interfaces config file (in Debian it is in /etc/network/interfaces). Or set it in your u-boot env:
fw_setenv ethaddr xx:xx:xx:xx:x
If one was assigned and it's not the same as one on the sticker, then it was assigned by the kernel, or u-boot temporarily.
