Implementing the delay in the PHY is just a recommendation, not a
requirement. However, as i said, you need to be careful what is pass
to phylib. If the MAC is implementing "rgmii-id", whatever makes it
way down to phy_attach_direct() needs to be "rgmii". If the MAC
implements "rgmii-rxid", the phy should be implementing "rgmii-txid",
etc. If this is wrong, you get both the MAC and the PHY implementing
delays, and bad things happen.
