This looks mostly fine to me, thanks for working on this. I do have one question though. At least to some extent the user will have to have a way to figure out that multiple interfaces correspond to one instance of the TCAM. Because this determines sharing and other aspects, right? How it seems to work in your description is that the user operates on (for example) eth0 and eth1 as if they were independant objects, but if the TCAM fills up that will be seen equally by operations on both interfaces. But, to be honest this is a minor detail. They may also be value in allowing TCAM entries to be locked by the kernel and thus be unmodifyable by the user. For example, in NIU, those special workaround entries we add to handle IP fragments would be a candidate for this. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
