Subject[PATCH] net: fec: Keep device numbering consistent with datasheet
Date
From: Christian Hemp <c.hemp@phytec.de>

Make use of device tree alias for device enumeration to keep the device
order consistent with the naming in the datasheet.

Otherwise for the i.MX 6UL/ULL the ENET1 interface is enumerated as eth1
and ENET2 as eth0.
