+Subject: [PATCH] net: phy: at803x: fix feature detection
+
+AR8031/AR8033 have different status registers for copper
+and fiber operation. However, the extended status register
+is the same for both operation modes.
+
+As a result of that, ESTATUS_1000_XFULL is set to 1 even when
+operating in copper TP mode.
+
+Remove this mode from the supported link modes, as this driver
+currently only supports copper operation.
