Hello James, A year ago, you wrote that patch: https://www.linux-mips.org/archives/linux-mips/2017-06/msg00658.html You called it a hack but it has been used since then. As you will certainly realize by now, Ocelot is one of the affected SoC so we would pretty much like to see this going upstream. What would be the way forward?
