Currently the fixed-link DT binding is pre-configured and cannot be changed in run-time. This means the cable unplug events are not being detected, and the link parameters can't be negotiated. The following patches are needed when mvneta is used in fixed-link mode (without MDIO). They add an API to fixed_phy that allows to update status, and use that API in the mvneta driver when parsing the SGMII in-band status. There is also another implementation that doesn't add any API and does everything in mvneta driver locally: https://lkml.org/lkml/2015/3/31/327 I'll let people decide which approach is better. No strong opinion on my side.
