This patch fixes an issue seen with the realtek 8201 phy. This phy has a
problem with crossover detection and it needs to be disabled. The
problem only arises on certain switches. Therefore, a module parameter
has been added to allow enabling crossover detection if needed. The
default will be set to disabled.
