+This is a hack to make cpmac work with the external switch on a DG834 v3; it
+should also work on other similar routers. It has not been tested on hardware
+with multiple cpmac devices or with no external switch. It may be safer to
+move external_switch to pdata rather than trying to detect it, and to set
+phy_mask correctly rather than moving the phy search loop.
