From: Vladimir Oltean vladimir.oltean@nxp.com
Unlike the Linux fixed PHY driver, the one in U-Boot does not attempt to emulate the clause 22 register set of a gigabit copper PHY driver through the swphy framework. Therefore, the limitation of being unable to support speeds higher than gigabit in fixed-link does not apply to the U-Boot fixed PHY driver. This makes the fixed-link U-Boot implementation more similar to the one from phylink, which can work with any valid link speed.
