I have couple of questions: Do you also plan to introduce support for FM6000? >From what I understand, there is one netdev instance for the whole switch (PF). How can user get stats and info for particular ports? This topic was discussed many times and I believe that general consensus is to have 1 netdev instance to represent one switch port (that is for example how we do it in rocker driver).
