[PATCH 19/20] bootwrapper: Only print MAC addresses when the node is actually present.

[Scott Wood]

Some firmwares (such as PlanetCore) only provide a base MAC address, and
expect the kernel to set certain bits to generate the addresses for the
other ports.  As such, MAC addresses are generated that may not correspond
to actual hardware.
