In most cases the network interface still worked, despite the MAC being different of what was specified to QEMU, but when some other host or DHCP server expected a specific MAC, this would fail. This change fixes this by shifting right by 2 the local-mac-address read = from device tree, if its length is 6 instead of 8, as observed in QEMU DT, that always presents a 6 bytes value for this property.
