+ Force master mode for 1000BASE-T on RTl8211x PHYs (except for RTL8211F).
+ This can work around link stability and data corruption issues on gigabit
+ links which can occur in slave mode on certain PHYs, e.g. on the
+ RTL8211C(L).
+
+ Please note that two directly connected devices (i.e. via crossover cable)
+ will not be able to establish a link between each other if they both force
+ master mode. Multiple devices forcing master mode when connected by a
+ network switch do not pose a problem as the switch configures its affected
+ ports into slave mode.
+
+ This option only affects gigabit links. If you must establish a direct
+ connection between two devices which both force master mode, try forcing
+ the link speed to 100MBit/s.
+
+ If unsure, say N.
