From: Thierry Reding <treding@xxxxxxxxxx>
The EQOS hardware block found on Tegra194 is in fact not compatible with
the instantiation on Tegra186. While the register programming is exactly
the same, one notable difference is that on Tegra194 only 39 bits out of
the advertised 40 bits can be used. Bit 39 enables some on-the-fly
swizzling of data that is counter-productive to ethernet connectivity.
