The RTL8211B seems to have a bug that prevents the link from coming up unless the MII_MMD_DATA register is cleared. The Linux kernel driver applies this workaround (in rtl8211b_resume()) only to the specific RTL8211B PHY model, along with a matching workaround to set bit 9 of MII_MMD_DATA when suspending the PHY. Since we have no need to ever suspend the PHY, and since writing a zero ought to be harmless, we just clear the register unconditionally.
