The 0x1 for TX is the hardware reset default from the datasheet, not
a value we choose for RGMII mode. For PHY_INTERFACE_MODE_RGMII, we
explicitly set both delays to 0.
Sorry, could you please advise me should I explicitly set TX delay in this case
to 0 or the default value specified in the datasheet == 1 (150ps)?
Thank you for your review!
