This lane is connected to a SFP cage which can support more than just 2500base-X. Tying it in this way to 2500base-X means that this port does not support conenctions at 1000base-X, despite that's one of the most popular and more standardised speeds.
What do you suggest to describe this in the dt, to enable a port using the current PPv2 driver? Antoine -- Antoine Ténart, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
