so this means that the phy is found and the link auto-negotiated.
Gabriel, it sounds that the patch solved a regression you found on
a configuration where the MAC dialogs with a switch but it breaks the
setup with use a std transceiver.

hmm, this could be another problem. I wonder if you can
check which recent patch is introducing the problem on ARM64.
For example if this depends on Oct_2015 update.
If you share some logs to me I can take a look at them.
Then we can try to check if the problem in on rx or tx path.
I also ask you yo check the axi settings.
Let me know
