The bootloader on ts209 Orion boards doesn't configure the right ethernet MAC address into the GigE unit on boot. The only way to get the MAC address is by parsing it from the 'NAS Config' flash partition, which is an ext2 partition that contains a file which holds the MAC address in plain text (format "xx:xx:xx:xx:xx:xx\n") -- this patch does that.
