Hrm.  linux,network-index was mentioned in b-w-o.txt, but to be honest
I don't think it ever belonged there.  It describes a bootloader to
kernel interface, whereas network-index was always a bootwrapper
internal hack, applicable only when the device tree and the fixup code
were built into the one image.

aliases, on the other hand do warrent wider mention, and aren't
mentioned at all in b-w-o.txt, but that's a matter of larger scope
than just getting rid of the network-index hack.
