+	  Force master mode for 1000BASE-T on RTl8211x PHYs.
+	  This is helpful for unstable gigabit links, e.g. on the

+	  If two devices force master mode, they will not be able to establish
+	  a direct link between themselves. In this case, either:
+	   - live with an unstable link and disable this option
+	   - reduce link speed to 100MBit/s
+	   - use a switch

+	  Does not apply to RTL8211F.
