u-boot passes this information to Linux in the board info (bd_t)
structure at boot time.  A lot of Linux ethernet drivers read the MAC
out of this structure and then set it in the hardware/software.

Very few u-boot ethernet drivers set the MAC in the hardware themselves.

With FreeBSD this mechanism is missing.
