If it can be done reasonably easy, which you patches seem to indicate is the case, I have no objections to extending packet socket for 64-bit timestamps. I hope that AF_CAPTURE will be designed in such a way that all apps can migrate to it, and I will be making sure it is implemented appropriately with that in mind. But I don't think AF_CAPTURE should block your work here.
