They are very unlikely tho, due to their policy of not breaking userspace (whenever possible). If I understand correctly, the current state of affairs is that TPACKET_V3 is unsuitable for immediate mode. I'll try to research a bit more on this in the next few days, but I'm inclined to believe you and Guy know better about it. We could try and work something out with the kernel bunch to make it suitable, but I don't think I know enough to push that forward by myself. Maybe (haven't checked) TPACKET_V4 can be used, but I think that's too recent to require from downstream to get immediate mode working. _______________________________________________ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
