There is a patch/bug cascade in the realtek target phy code that must be resolved. 1. The phy_driver structure is patched to add features ONLY needed for RTL8214FC 2. The kernel is patched to allow switching fiber/copper port of phys through ethtool by calling these new features. 3. With those patches applied the bootup always switches RTL8214FC ports to copper. Even if a SFP module was found before and the phy driver switched to fibre before. 3. So another patch is needed that reprobes the SFP module to activate fiber again. 4. Because of the reprobing we need a fourth patch that avoid duplicate devices. Simplify this by removing all patches and reusing the existing ethtool phy tunable interface. The command line usage might be counterintuitive but it avoids tons of problems in the code. In addition, this scenario is not used frequently.
