Roopas patche's are about new class of device which, as I commented in the cover letter, I left out for now and can be safely added later on. I went over the Ben's work very carefully as well. The patches are very rough, mostly rtl-chip specific. But again, my patchset is a base on which this patches can be build on. I see no issues in that. >At least please get their sign on - this is such an important piece of >new work that you should make sure you get consensus. Since I did not use their code now, I only put sign off of Scott. >Otherwise we are back to square one and everyone is going their way with >their patches; I do think that we are in sync. I do not see any counter ways.
