+Subject: [PATCH] net: phy: broadcom: Add BCM54810 PHY entry
+
+The BCM54810 PHY requires some semi-unique configuration, which results
+in some additional configuration in addition to the standard config.
+Also, some users of the BCM54810 require the PHY lanes to be swapped.
+Since there is no way to detect this, add a device tree query to see if
+it is applicable.
