+Subject: [PATCH] net: thunderx: add support for rgmii internal delay modes
+
+The XCV_DLL_CTL is being configured with the assumption that
+phy-mode is rgmii-txid (PHY_INTERFACE_MODE_RGMII_TXID) which is not always
+the case.
+
+This patch parses the phy-mode property and uses it to configure CXV_DLL_CTL
+properly.

+While it is not yet understood why a TX underflow can easily occur
