Is it doing this in an endless cycle?

Exactly, so what I'm seeing is when the driver livelocks the macphy is
periodically pulling the irq pin low, the driver clears the interrupt
and repeat.

If I understand correctly, you are keep on getting interrupt without 
indicating anything in the footer?. Are you using LAN8650 Rev.B0 or B1?. 
If it is B0 then can you try with Rev.B1 once?

I'll check the footer content, thanks for the tip!

All testing has bee done with Rev.B0, we've located a set of B1 chips.
So we'll get on resoldering and rerunning the test scenario.
