I'm now currently testing your ar71xx 4.14 bump (comitted today in
master) on a few different targets:
- Gl-mifi
- Rocket-m5
- RB912
- RB2011
...
Will let you know the results.
Hi John,
I started with trying on a Mikrotik RB2011 as these have a Serial port.
Ethernet does not function correctly.
I see it transmitting packets, but receiving fails.

Hi John,
I've digged a little bit deeper into the issue and compared/tested the
driver code between 4.9 and 4.14
The main problem is that within ar8327_hw_config_pdata() [1]
pdata is NULL when this function gets called ..

I can confirm that the board_info data gets loaded in the list though.
No idea currently why platform_data would be NULL currently ..
