Hi Ian,

I've applied it to the sysutils/u-boot-rpi port and test the package
with the RPI-B. The configured usbethaddr is set in the u-boot
environment, but it will not passed to the kernel via the FTD blob. The
FreeBSD kernel always have the BIA of the NIC.

But I think, you are right, the RPis FTD data is available before the
u-boot enviroment is set.

So unfortunately that doesn't work a the moment.

Best regards,
