No. The name in DT should not give the name of the interface. It
should be possible to give this eth0 as expected, even if in DT it is
eth1. The names here are separate things. The kernel will assign a
name to the interface when it is registered to the network
stack. Since this is the first registered interface, if should get the
name eth0. What i think is happening is that something is later
renaming the interface to eth1. We have to find out what is doing this
rename.

So delete this entry and reboot. See if that helps.
