WebbThe Marvell 88E151x product brief Ethernet PHYs were designed with two internal delays which can be enabled to add skew to the incoming RGMII TX clock and the outgoing RGMII RX clock independently. The delay, regardless of link speed, is always 1.9ns.

WebbThe driver currently sets a MAC TX delay of 2 ns no matter what the phy-mode is. If the phy-mode indicates the phy is in charge of the TX delay (rgmii-txid, rgmii-id), don't do it in the MAC.
