When the zynq_gem driver initializes the phy it sets the supported features that the phy can support and advertise. However instead of masking the supported features such that it limits the available features it sets the phy to have the exact supported features of the zynq_gem. This is problematic as it will enable features that a phy does not have or cannot advertise. Specifically this appears as an issue when using a phy that is only capable of 10/100, but the zynq_gem driver will override this and try to enable and advertise 10/100/1000. Reported-by:
