I have been using the driver and LAN connection for the past few days (ssh)
and have had no problems.
The driver diff is below.
It works with a dtb that has the entries for emac listed below the diff. I
have no idea of how the "official" dtb will look like, so there may be
changes required for that. Also note Jonathan's comment about the
possibility of multiple physicals. The Orangepi-one only has one NIC port
and so it is not a concern there

So, do things work for you now? You should send the full diff you're
running with now.
