Certain serial SERDES protocols like 1000base-x, 2500base-x, SGMII, USXGMII can operate either in a mode where the PHY (be it on-board or inside an SFP module) passes the link parameters (speed, duplex, pause) to the MAC through in-band through control words standardized by IEEE 802.3 clause 37, or in a mode where the MAC must configure (force) its link parameters based on information obtained out-of-band (MDIO reads, guesswork etc). In Linux, the OF node property named "managed" is parsed by the phylink framework, and the convention is that if a driver uses phylink, then the presence of this property means that in-band autoneg should be enabled, otherwise it shouldn't. To be compatible with the OF node bindings of drivers that use phylink in Linux, introduce parsing support for this property in U-Boot too.
