I was going to put this into the next/late branch that already has some other
changes, but in the end I decided to drop it because it is based on
a later -rc release than the other branches, and doesn't seem obvious
or important enough.

Just a clarification about the contents of the patch, you write:

    Without having an ethernet alias, ethernet will have a random MAC address,
    versus take an address that was provided from the bootloader.

Why is the alias needed to get the right MAC address? How does the
bootloader pass it?

That's fine. I can queue it for v4.8.

For example, if U-Boot's ethaddr environment is set, the MAC address
gets populated in the mac-address property of the node with "ethernet"
alias.
