The MCU Ethernet Interface on J7200-EVM uses the DP83867 Ethernet PHY as described in the section '4.9 MCU Ethernet Interface' of the J7200-EVM User-Guide [0]. Since the config corresponding to the DP83867 PHY has not been enabled, the Generic PHY driver is used. As a result, the RGMII delays do not take effect leading to packet losses.
Fix this by enabling the config for the DP83867 Ethernet PHY.
