Hi Andrew,

Our purpose is to handle our internal pdata->phy_mode, so
phy_interface_is_rgmii(phydev) seems not to fit.
Instead, we're working on the below:

+bool is_xgene_enet_phy_mode_rgmii(struct net_device *ndev)
+{
+       struct xgene_enet_pdata *pdata = netdev_priv(ndev);
+
+       return pdata->phy_mode >= PHY_INTERFACE_MODE_RGMII &&
+              pdata->phy_mode <= PHY_INTERFACE_MODE_RGMII_TXID;
+}
+
