DPAA Ethernet traffice troubles with Linux kernel

[Christian Zigotzky]

Sorry, I have forgotten the download link. Please test it with the DPAA 
Ethernet.
Hi All,

I compiled the RC8 of kernel 4.15 with Joakim's patch for the AmigaOne 
X5000 today. Many thanks to Joakim for the mdio patch.

Download: http://www.xenosoft.de/uImage-4.15-rc8_with_mdio_patch.tar.gz

Please test it on your X5000.

Thanks,
Christian

Hi,

Please use text logs instead of pictures next time, it's easier to 
read.
The errors you see are related to missing MAC addresses for the unused
interfaces, you can ignore these are they are not relevant for the 
issue
you encounter. Normally the unused interfaces should have status 
disabled
in the device tree but there is not a big deal if they fail like that.
As I've advised Jamie on the other thread, please try to connect the 
device
back 2 back to a known good machine and determine what is broken - 
Rx/Tx?
Is there another software version that does work on these machines?
Hi, just saw this and thought of a small patch I just wrote for mdio 
bus, o idea
if it is relevant but here goes:

Subject: [PATCH] of_mdiobus_register: Continue after error

of_mdiobus_register unregister itself if one phy fails to register
which is bad for system having all its PHYs on the same MDIO bus.
Just log the error and continue with the remaining PHYs instead.
