The only successful examples seems to be where the user- > space code is maintained by a kernel developer, e.g., iproute. Isn't that the truth... Alexey was maintaining his own semi-fork of libpcap and tcpdump for years for the same reasons. Let's write a real packet capturing tool that will be fast and that we can add quick support for new kernel features to. I mean, what other alternative is there? The pcap/tcpdump folks have had 10+ years to get their act in gear. -- 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
