I defintely think that there should be a consumer of the queue API before it lands upstream, but if it cannot work without a driver/hardware support that seems a bit odd. Maybe I've missed it on the list, but do you have something you can share about this proposed queue API? > The point of the above is a list to motivate discussion based on recent > topics. > > > > Please leave them out of your fwctl session. > > fwctl is a discussion item not tied to anything else; let's not conflat > topics here.
