Hi Dan
It probably is not well documented, but one example would be
Documentation/devicetree/bindings/net/ethernet-controller.yaml
says:
# RX and TX delays are added by the MAC when required - rgmii
# RGMII with internal RX and TX delays provided by the PHY, # the MAC should not add the RX or TX delays in this case - rgmii-id
# RGMII with internal RX delay provided by the PHY, the MAC # should not add an RX delay in this case - rgmii-rxid
# RGMII with internal TX delay provided by the PHY, the MAC # should not add an TX delay in this case
