Odroidc1+ ethernet(dwc0) not working

[Weiß, Dr. Jürgen]

It seems the FreeBSD driver is only able to use the
mac address which is already programmed into the nic.
So if you use a command in u-boot, which needs and
initializes the network, FreeBSD uses the same mac
address as u-boot. If not it seems to be random.

Actually, this comment is from the driver:

         * Try to recover a MAC address from the running hardware. If there's
         * something non-zero there, assume the bootloader did the right thing
         * and just use it.
         *
         * Otherwise, set the address to a convenient locally assigned address,
         * 'bsd' + random 24 low-order bits.  'b' is 0x62, which has the locally
         * assigned bit set, and the broadcast/multicast bit clear.
         */
