- *
- * If AU1XXX_PHY_STATIC_CONFIG is undefined, the PHY setup is
- * autodetected:
- *
- * mii_probe() first searches the current MAC's MII bus for a PHY,
- * selecting the first (or last, if AU1XXX_PHY_SEARCH_HIGHEST_ADDR is
- * defined) PHY address not already claimed by another netdev.
- *
- * If nothing was found that way when searching for the 2nd ethernet
- * controller's PHY and AU1XXX_PHY1_SEARCH_ON_MAC0 is defined, then
- * the first MII bus is searched as well for an unclaimed PHY; this is
- * needed in case of a dual-PHY accessible only through the MAC0's MII
- * bus.
- *
- * Finally, if no PHY is found, then the corresponding ethernet
- * controller is not registered to the network subsystem.
+/* FIXME
+ * All of the PHY code really should be detached from the MAC
+ * code.
