Merge branch 'ethoc-next'

Florian Fainelli says:

====================
net: ethoc: Misc improvements

This patch series fixes/improves a few things:

- implement a proper PHYLIB adjust_link callback to set the duplex mode
  accordingly
- do not open code the fetching of a MAC address in OF/DT environments
- demote an error message that occurs more frequently than expected in low
  CPU/memory/bandwidth environments

Tested on a Cirrus Logic EP93xx / TS7300 board.
