+Subject: [PATCH] ath79: force SGMII SerDes mode to MAC operation
+
+The mode on the SGMII SerDes on the QCA9563 is 1000 Base-X by default.
+This only allows for 1000 Mbit/s links, however when used with an SGMII
+PHY in 100 Mbit/s link mode, the link remains dead.
+
+This strictly has nothing to do with the SerDes calibration, however it
+is done at the same point in the QCA reference U-Boot which is the
+blueprint for everything happening here. As the current state is more or
+less a hack, this should be fine.
+
+This fixes the issues outlined above on a TP-Link EAP-225 Outdoor.
