Just to make sure I re-tested Nov 4th and I couldn't reproduce the problem
anymore. Not even moving connecting the bananapi to same switch port and
using LCD/USB keyboard (just in case). It always got GigE interface
working immediately independend of wether rgephy attached at id 0 or not.
I.e. with a kernel from before the change to sunxi_gmac.c and with a kernel
from after the change. It was perfectly reproducible before the weekend.
I'm not sure what changed. The switch didn't reboot or reconfigure in
that timeframe either.
