As Andrew already pointed out, we'd like to know if networking for this
board works without any further adjustment of the RX internal delay.

This was necessary for VisionFive (see previous PATCH v2 11/12), but the
PHY is different (Motorcomm YT8521), hence this test might help us
understand if there's a potential issue with the SoC or the PHY.
