+Subject: [PATCH] net: bcmgenet: Clear ID_MODE_DIS in
+ EXT_RGMII_OOB_CTRL when not needed
+
+commit 402482a6a78e5c61d8a2ec6311fc5b4aca392cd6 upstream.
+
+Outdated Raspberry Pi 4 firmware might configure the external PHY as
+rgmii although the kernel currently sets it as rgmii-rxid. This makes
+connections unreliable as ID_MODE_DIS is left enabled. To avoid this,
+explicitly clear that bit whenever we don't need it.
+
+Fixes: da38802211cc ("net: bcmgenet: Add RGMII_RXID support")
