net: phy: Optionally force master mode for RTL PHY
This patch introduces CONFIG_RTL8211X_PHY_FORCE_MASTER. If this define is set, RTL8211x PHYs (except for the RTL8211F) will have their 1000BASE-T master/slave autonegotiation disabled and forced to master mode. This is helpful for PHYs like the RTL8211C which produce unstable links in slave mode. Such problems have been found on the A20-Olimex-SOM-EVB and A20-OLinuXino-Lime2. There is no proper way to identify affected PHYs in software as the RTL8211C shares its UID with the RTL8211B. Thus, this fix requires the introduction of an #ifdef.
